I installed my V4 power tailgate (without foot sensor) over 2 days on the weekend. Overall I took 12-14hrs to complete the install but I took it real slow. Now that I've done it, I could probably do another one in under 6hrs.
Here are my tips from my installation.
Here are my tips from my installation.
- Have extra pry tools than just the one orange one Hansshow provides in the kit. I have a set of 4 from my ICE days. They come in handy with trying to extract the white clips that from the trunk lid.
- The trunk lid trim is secured with an insane number of clips (okay, 11; 7 greens and 4 whites). You're likely to break at least one green clip (Hansshow gives you 2 spares), and all of my 4 white clips came off from the trim and remained on the lid.
You need to extract the 4 white clips and put them back on the trim before you can attach the trim back onto the lid. It was a real PITA to extract the white clips. - Removing the tailgate button plug from the wire made it a lot easier to fish the wire (and the tailgate handle+lock motor (bare) wires) thru the rubber tubing. Detaching the rubber tubing from the cable ties using a metal pick as per the Electrified Garage video (I happened to have the same pick) made it a lot easier to thread the fish tape thru the tubing.
- I followed the Hansshow V4 trunk installation video and run the struct cables down the sides thru the gap between the chassis and bumper and coming into the trunk thru the 2 holes that were covered by blue grommets.
Note that the left circular hole is smaller than the right larger oblong hole .
Each struct has 2 plugs that are different sizes. The smaller hole is just big enough for the just bigger plug to get thru; tape the plugs to the fish tape as follows to be as streamlined as possible.
In hindsight, it might have been easier with the plugs removed, however, I don't know if they're as easy to remove as the tailgate button plug. - I didn't pull the struct wires taut thru the grommets. I left a bit of slack hoping that'll result in a drip loop to prevent water ingress into the trunk (though there's no way I could visually confirm that). I used silicone to seal the holes in the grommets.
- The small gap between the chassis and bumper is made smaller by a piece of rigid plastic. You need to gently nudge the plastic away from the chassis (maybe not so gently) using a pry tool so the plugs that are taped to the fish tape can get thru the gap.
- Following the EG video, I connected the battery power (B+) wire to the red terminal beneath the rear seats. I ran just enough wire to reach the terminal; the remaining length of the wire is bunched up and cable-tied next to the control box in the trunk.
- I connected the CANBUS cable behind the centre console. The Hansshow video doesn't show how to route the FRONT CAN wire to the centre console. I was able to run it along the right side beneath the door trim, across the base of the B pillar towards the driver's seat (for a RHD Model 3). There's an overlap in the floor carpet (see red arrow below). I lifted the trim to the right of the blue arrow and could see a harness going underneath the driver's seat.
Using the fish tape I routed the FRONT CAN wire underneath the seat rail. From there I hand-threaded the wire underneath the other rail and connected the plug to one of the CANBUS sockets from the middle console. I tucked the cable beneath the floor carpet.
All you can see is a bit of cable between the centre console and left rail of the driver seat.
