DIY: V1 Hardwire 997 with auto dimming mirror (NO SOLDERING!)

Thanks to member skeeter for walking me through this. This is his mod, I just took the pics while I did it

There was a very elegant hardwire thread on Renntech that involved a lot of cutting and soldering....

Yeah....wasn't too comfortable with that. Couldn't believe that no one posted a V1 hardwire using the V1 kit. To my knowledge, one doesn't exist. Well, here it is:

Tools needed:

Small flathead screwdriver

Phillips screwdriver

Pliers

V1 Hardwire kit

1) Remove the dome light cluster
I used a small flathead screwdriver up by the windshield to gently release the clips and remove the lights.

2) Remove the homelink buttons

There is a small tab along side each button cluster (indicated by red arrow). Use a small flathead to pop these out. They come out with very little effort.

3) Remove the Phillips head screws

After removing the buttons, you will see a Phillips head screw under each button cluster. Remove these.

4) Remove plastic dome cover

Sorry, no pic of this. Get a flathead screwdriver or your fingers under the dome cover back by the sunroof and gently (but firmly) pull down. It is held by two clips a few inches from the back and hooks in the front by the windshield. I was afraid of breaking the thing, but it eventually came loose

5) Find the ORANGE/BLACK hot wire

This wire is located in the cluster of wires coming out of the headliner on the driver's side. Cut or push the black tape aside to find it and get enough slack to attach the T-tap connector.

6) Attach the ground

This is PITA Using the metal clip on the passenger side where you removed the Phillips head screw, slowly slide the clip part way towards the passenger side. To prevent it from flying under the headliner if you accidentally remove it completely, stuff a small microfiber or paper towel in the space just to the right of the clip.

Now, using the flathead, pry open a space between the clip and the chassis. Then slide the spade connector from the hardwire kit into this space. Push the clip back to the left to line up the screw hole with the hole in the clip.

7) Test it

Without putting all the lights and panels back just yet, put the Phillips head screw back into the passenger side hole to hold and compress the ground to get a good connection.

Fire up the car and VOILA! Just remember to remove the screw again before you replace the dome cover.

Mine didn't work at first. Had to pinch the T-tap with pliers to adequately cut through the insulation of the hot wire. Other than that, just make sure the ground screw is in tight and it should work.

8) Route phone power cord out the front and STUFF the wires under the headliner

Route a short length of the straight cord out through the front hole by the mirror stalk.

Now to get the wires tucked...Ok, this is PITA too. If you haven't already noticed, there isn't a lot of room up there. But if you look under the headliner under the passenger side vanity mirror, there is some room to stuff all the wires. This took some doing with a VERY tight fit, but it works.

9) Reverse the removal steps.

Clip the plastic dome piece into place, replace Phillips head screws, replace buttons and dome light.

Now you can enjoy V1 hardwired goodness

Decided to tackle the V1 concealed display since it wasn't 120 degrees outside today

Mounted it on top of the steering column.  

Then fed it between the trim above the ignition/light controls, under the A-pillar, across the headliner and back into the power supply in the dome cluster. Will try to tidy up the wire as it wraps around the driver's side air vent, but as it is, you can only see it if the door is open.



Remounted the main unit to the right of the rear view mirror.  

Fired it up and works perfectly!



Actually would have preferred to more 'stealthily' mount it in the little storage compartment below the climate controls, but I couldn't figure out a way to adequately route and tuck away the wire.
