A little interior lighting mod

Hey everyone!!

a few months ago, I picked up my P85D, and like many owners here, I feel like for such a high tech, and innovative car, the interior is a little underwhelming. I know minimalism is key for the design, but a piece of me just wanted a little tiny bit of flair to give it a little edge.

so this is what I did...

I wanted something subtle so I went and picked up a few EL wire kits and ran them across the trim in the dashboard and doors. This was insanely easy, and after learning where things were, and getting things fished through, they can be installed/uninstalled in under 30 minutes. The best part is just how OEM they look. They are a dim white and have a very soft glow, so it’s not distracting or overbearing. They are linked into the premium lighting, so they can be controlled with the display. Lowering the brightness dims them, and turning off ambient lights turns them off.

every single person who has sat in the car comments on “how cool the trim lights in Teslas are” only to be surprised when I tell them it’s not a standard thing.

I know not everyone will like them, or think they are “cool” but if there’s someone out there that also wants to spice up the interior in a subtle way, this is an awesome (and cheap) option. Overall, the parts needed to do this are ~$50 for all 4 doors, the dashboard and the tools to do it (basic ratchet set and panel pullers)

oh, and during the day, they blend so well with the trim that they are almost invisible. There’s a very feint coppery-gold filament inside the wire that’s visible, but it’s undetectable unless you’re close and looking for it. It’s quite satisfying driving through a tunnel and seeing them pop on out of nowhere.

and I know I need to vacuum the car...idk how but sand just finds it’s way in no matter where I go lol.

cheers!!

I would like to know what kit you used as well! I would be interested in trying this out on Sparrow.
 
A few people have expressed interest so here is a part list and write up on how to do this.

The lights: Flexible Neon LED Light Glow EL Wire String Strip Rope Tube Car Garden Outdoor | eBay

4x 2m 12V inverter
1x 3m 12 Inverter
Color: White

(YOU CAN GET ANY COLOR YOU WANT, BUT WHITE IS THE MOST FACTORY LOOKING)

These are the exact ones i purchased, but when i bought them, they were only $5 per 2m rope...so the prices have gone up for this vendor. Most of these kits are the same, so if you're feeling adventurous, you can definitely find them cheaper. You're going to want the 12V inverter kit. It comes with a little black box, and two open wires to splice into the accessory line in the door panel so it will work with the ambient lights.

Optional:

Extension pigtails: Extension cables ('pig tails') - one pair

These were important for me, but not NEEDED in the installation. They accomplish two objectives here.
1: Working in the door can be very cramped, and trying to splice into the existing wires can be a headache since there isn't a lot of slack, or room to work. These allow you to do all the electrical splicing outside the car, at a table or workbench. Then you can just connect them to the existing harness for a seamless install.

2: They make the install removable in an instant. If for any reason a light strip gets damaged, or goes bad, you can simple disconnect it, and re-attach a new one with NO more splicing. It also preserves the integrity of the original hardware, which can help if you're getting service done, and you're paranoid like i am about them saying something. Simply remove the modded bit, and re-plug the original and you're good to go.

Insulation

I don't have a link for this, because there are a lot of options to consider. You see, since these are 12v inverter boxes made in China, they are not of the highest quality, and as such they make a very irritating high pitch whine. It's not super loud, but it's definitely noticeable if you don't take steps to silence them. (Especially when there's 5 of them in the car) Here's what i did.

I picked up some fireproof, soundproof insulation from Lowes, and a rag. I made a little pouch and tape wrapped the transformer box nice and tight. This added a lot of bulk to the box, but it practically eliminated the whine.

Here's what some others have done:

If you break apart the transformer, you can seal the capacitor in glue, which helps deaden the whine.
You can also cover the whole thing in layers of glue (I don't think it's worth the mess)
I have also heard of people building these from scratch with much higher quality parts (Way outside my skill level)

I tell you this now, because if you're considering the install, the first time you put these in, it will probably take a little while. Getting into the door is easy, but wiring, and testing, and realizing you accidentally swapped the polarity, and having to go back, then forgetting to reconnect the harness...trust me...it's going to happen lol. The last thing you want to do after all that is go out, and sit in your new futuristic spaceship mobile, and hear this feint whine eeeeeking away at your soul. The satisfaction after insulating these is well worth the extra step.


The actual install.

If you haven't been inside the door, it's extremely easy to get in. There are how-tos here that were super helpful for me.


Once you're inside the door, you can opt to disconnect the cables and retaining band that you may or may not have and give yourself some more room, or (If you used the extension pigtails) you can just reach in, and pull the accessory wiring from the ambient lights in the arm rest and connect your fancy spliced one on the end. There was a remarkably small number of wires inside the door, so really, just find the one by the armrest and that's your ticket. It's also the same as the pigtail if you were working with it, then you'll know exactly what im talking about.

For the doors, the lights are easy to get where you want them. Find a spot to secure the transformer box (I tested out a few locations and the best ones are up top by the mirror, there's some empty space there that doesn't cause to much trouble, and in the centerline, slightly lower then halfway there's a spot where you can push in the insulation. The box can sit nicely there, but depending on how bulky your insulation job was, you may have to poke around to find a good spot for it. This is VERY important because if you secure it in a spot where it doesn't have enough space, it will prevent the door panel from being completely secured. It will give you a gap at some of the clips, and it will squeak every time you go over a bump. wrap the wire around the groove in the door panel, and make it nice and flush. You will need to be firm and patient to work the little tail into the groove, as it is very tight.

The dashboard is a little bit more complicated. I went in through the passenger's side. Remove the door sill, and the panel hiding the fuse box in the passenger foot well. SEE:
once the panels are removed, you can access the cable passthrough. and feed it through The cable passthrough is PACKED, and there is a 0% chance of getting through it, so i went around it. What i did was CAREFULLY remove one small "corner" of the rubber grommet that holds it in place, just to get enough space to force the wire through. Once it's through one end, simply push the grommet back into place (Will take some force) and do the same for the other side.
IMG_0673.JPG IMG_0674.JPG

Here's a tip. Pop open the grommet, and feed a dowel, or some thick zip ties through the opening. You will see it poking through from the passenger side well by the fusebox. Tape the connector end of the light strip to the end of the dowel/zip and then pull it through. Saves a huge hassle.

Once you have passed through the door side grommet, it's time to go fishing. By the small window, there's a rubber seal that hides a hole that you can see into the case of the door. At the bottom is the cable passthrough, and if you fed the other end of the cable, your connector. It took me 20 minutes to fish it up to the top with a few zip ties. If you can get a hook on a dowel, do that because it's WAY easier. Once you get the connector up through the door, and into the panel area, you can attach your transformer and you're all set. All you have to do is run the light itself up the side by where the fuse box is, and wrap it around the dash trim. Take some time to hide any excess light, and make it as seamless as possible. Start from one and, and make it nice and flush all the way through.

You will have 2 transformers in the passenger's door, so be sure that they are placed perfectly so you don't have the panel gap on the door. I know this seems like a lot, but really it's just a lot of patience and unfortunately trial and error. The spots that worked for me, may not for you, and my trim may have been a bit looser, or tighter than yours will be, so working the lights into the trim may be more or less work. I found that starting at one end, and "massaging" it into place worked best. In some areas i actually needed to pry a bit to make them set better.

Since these lights are not super bright, their shape is VERY showing of imperfections and kinks. It's painfully obvious if it's not seated evenly, or if there's any bends. If you ever look up EL wire lighting in a car... it's almost 100% of the time an obnoxious outline of an entire piece, making a box outline (Which i hate) and it always looks like it was hand drawn with all the kinks and imperfections. Take your time, and you will have a SMOOTH, EVEN, and FACTORY looking effect.

I also realize that i wrote a damn book. If there's any questions, or anything that needs more explaining, please let me know. I have no problem taking pictures, or maybe make a video on this install if it would help y'all out. :)

I can't wait to see if y'all go for this, and how it looks!!!
 
Last question=is the front dash lighting 2 pieces or one...don't see any light across the speedometer display..thanks in advance for your help....

Of course!!

Q1: So the EL wire is actually significantly longer than necessary, so trimming it is needed. Fortunately, it's as easy as cutting it with a pair of scissors. I usually cut them on an angle just because it makes them fit better.

Q2: The lights have in essence, a "Teardrop" shape, where the part that lights up is a rounded piece with the phosphorus running through it, and then there's a "tail" that is a very thin plastic. If you insert the thin end into the gap between the trim pieces, and firmly press into them, they slide into that gap. This does two things. It holds the lights in place, and it actually secures the space between the trim pieces, reducing rattle and/or wobble. Once you get them in your hand, it makes a lot more sense. There's no gluing or adhesive here. You can even take them out, and re-position them if you need to. Just note; it's VERY important to have a smooth finish. Parts of the trim will be closer together, and it will be harder to work the tail into the gap, in these cases you can carefully spread them apart with a panel puller (VERY CAREFULLY) you don't need to rip it up, but just enough to guide the strip. You want little to no kinks for the best look.

Q3: The dashboard was a personal preference of mine. Above the instrument cluster, there is no "Pinching" trim like there is on the rest of the dash, and door lines. This makes the wire very hard to get kinkless, and overall just kind of ruins the look for me. So what i did, was i took one longer piece of lighting, and started from the passenger's side, and when i got to the instrument cluster, i actually went down, and behind the plastic bezel, and then under the steering wheel column before coming up the left side and continuing into the dash. It still looks a little off to me, and it's the only spot where it's not PERFECT, but it looks significantly better this way in my opinion. The light that goes behind the bezel, and steering wheel column also gives off a very soft and feint glow around the cluster, which is extremely subtle, but pleasant. You can't see the actual light, only the reflection (since i have a gloss finish i was worried, but it worked out in the end.)

Please feel free to ask as many questions as possible, i wish i had someone to ask when i was doing it, because i had to set up, and re-set up these things 5 or 6 times before i got them how i wanted them lol.

I'm totally stealing this idea... this week. Looks awesome. I would not recommend going around the grommet, tat may cut the wire over time. Oil it up and run it through the factory rubber (I ran camera wires through there), other then that EXCELLENT.

One question, how does it look in daylight?

One thing... I'D run the wire inside the door grommet. Over time it will cut the wire if ya don't. Use oil and a fish it'll go through but otherwise . EXCELLENT.
I was worried about this, so i wrapped the entire wire in electrical tape. I know it's a band-aid solution, but for now it works. If you can oil it up and do it, i'd say 100% go for it...i will likely try and fix it sometime lol.

Side note; did you install the 360 cam system?? Seriously debating that as my next project.
 
@VelociRabbitt How's your dashcam? I returned a DR900S because I could not get a GPS signal.
The Dashcam is perfect for what i use it for. I only use it for parking security, since i commute to campus, and park in a huge parking lot with a bunch of college kids, i wanted something so if i come out, and my car is smashed up, there's something to reference. So for me i didn't really need the GPS function, rather than just a security parking cam. I believe it's the Blackvue 850?

I did.. and have since removed it so if you want one cheap I have one in a box. :)
