Hey guys,
I needed to hardwire the V1 in my Plaid X and couldn't really find any info on install/wiring for the refreshed models. Hopefully this post helps the next person out:)

PARTS USED:
-Valentine V1 (gen2)
-Blendmount BV1-2035
-6Ft 14AWG red+black wire
-2 Wire taps


After installing one on my 2018 X, I was hoping the wiring in the overhead mirror was the same on the refreshed. Nope. I couldn't find any stable switched power in the mirror so unfortunately the power wire will need to go down to the center console. Inside the console is the CIG lighter, which is a switched 12V feed and on it's own fuse which will be perfect to tap off. Down side, install is a little more tedious(not hard) as you will have to route the wire a little further.

Install;

remove the small plastic bezel around the mirror base(unclips) then rotate the entire mirror counter clockwise and it will pop off from the base. Final step is to unclip the larger plastic surround. exposing all the sensors/wires mounted on the glass

pop the center plastic bar off(that holds all the wires) and route the new radar power wire through

Reinstall plastic and have wire exit

the wire will be routed this way. It's small and easy to tuck in between the panels

The power wire for my V1 was a little short and ended up at the drivers B pillar. I didn't feel like ordering a longer one and waiting, so I opted to mount the power connector/junction in there.

more than enough room to mount it

I used about 6ft of power/ground and enclosed it in some wire loom

Route the power wires down and under the door sill panel. there is a split in the carper under the seat that is perfect to tuck the wire in

The wire will end up going forward under the seat and into the console

In the center console the whole panel that holds the USB-C and CIG outlet pops off.

Fish your power wires up into the cavity and Unplug the grey connector so it's easier to work with. Now you can use the wire tap method of your choice. Tesla made it easy, RED +12V and BROWN- Ground.

Install the bracket for your radar detector and plug it in! Done

There is a lot of info on Model S Refresh.

There is a spot to tap in the mirror that powers the camera board in the mirror. I can’t imagine that same power source doesn’t exist on the Model X Refresh.

See 12V Access: Model S 2021 Refresh
Thanks for the info. I metered those wires with my Fluke and I got 15V constant. Circuit wouldn't shut off when doors were closed and locked.(although I didn't check/wait until the car went to full sleep mode). I feel more comfortable tapping off an AUX power like CIG lighter and know 100% it's switched.

Alternatively you can pop the right side center console and tap the same aux wire that runs to the back. Then you can just run wire up the front A pillars, up to the headliner, and down the center channel.

I've searched through your past threads to see if one started out mentioning how you hard wired from your prior X. I've got a '17 and I just picked up a Uniden detector that I'd like to hardware. Do you have a writeup for dummies (parts needed to buy, wire colors, etc) somewhere that I missed? Also, did you have to buy an aftermarket cord or did you cut up the phone style connecter at the cigarette lighter plug?

I feel more comfortable running way less wires for service to spot and void warranties. ICE cars often run above 14V because that’s what they charge the 12V at. So V1 handles the 15V fine. Turns off and on perfectly. Cigarette lighter sockets have had issues not “turning off” too. So it does not mean your immune to those types of issues. On Model 3 folks tapped cigarette socket and then later a software update changed the behavior and it didn’t turn off.
