Anyone do it? Is the wiring harness there just not connected? I was going to try it but I dont want to get my hopes up.

 

I would like to know also

 

I believe the problems are the mounting points on the windshields. I remember someone on this forum tried and found out the windshields are different on cars with premium and non premium with different mounting brackets on the mirrors.

 

huh, ok. Otherwise I was thinking about buying one aftermarket and installing it, maybe something with autodim. Sucks to have such a nice car that doesnt even have a nice rearview. My grand prix even did haha.

 

I have had a homelink OEM FX mirror installed in my car for almost six years, a local stereo shop installed it. I believe they just needed to splice in to power, and they used a plastic track to cover up the wire going up to the headliner. Looks and works OEM

 

I installed one in my wife's car just a few weeks ago. It's fairly easy. The window mount is identical.

If you can get the harness to plug in the back it's a piece of cake, if you can't, you have to get a little creative with small crimp-on connectors to power it.

I just ran power and ground wires from the sun-shade vanity lights power wires - which is not an exact power solution, as it is somewhere between the "Always-on" power that the garage door opener wants, and the accessory power that the auto-dim mirror wants. The power for the lights on the sun-shields turns on when a door gets opened or the key is in the ON position, and turns off 10 min after the car is off and the door is shut. It's never caused an issue at all being connected this way.

If you're buying one from somebody here, try to get the little plastic wire cover that goes between the rear view mirror mount, it will help it look OEM, and of course, the previously mentioned power harness that plugs in the back.

 

I have two for sale if anyone is interested.

 

I know this is an old thread but wanted to bump it with some additional info. Thanks to Wathernaut for the idea! Sorry for not taking any pictures.

I just did this swap today on a base sedan. I can confirm that there is no harness for the homelink mirror. If you have the mirror harness, then this is a piece of cake, once you know what you're doing and have enough access to work with. If you're not sure, refer to the service manual for instructions on how to remove the specific interior pieces I mention.

First thing first, remove the standard mirror. There is a plastic clip that latches onto the windshield base. You'll need to push this in. It'll take quite a bit of force, so make sure you are angled so you can see what you're doing and not slip off. Next, take off both the driver side and passenger side sun visor clip. You will need to remove the passenger side sunvisor, but you can leave the driver side on, if you choose. Take off the passenger side grip handle as well. Then you'll need to pop off the passenger side "A" pillar trim piece.

The next step is to slowly work the headliner away from the metal roof. Note: there is a plastic card holder that sits under the passenger side sunvisor that just pops off. I found it easiest to slowly apply force from the edge of the headliner and work the plastic cardholder slowly until it popped off. There is a plug that is attached to it and slides right off the mount point. That plug powers the sunvisor vanity lights and map lights. Pull the headliner out from passenger side door trim. If you have a sun roof, you'll need to pull the rubber trim piece. Do NOT pull it all off, just the front section and the front passenger corner is all you need. Just let it hang there or open the sun roof and tuck it out of the way.

Now, if you sit in the passenger seat with your back to the windshield, you can pull down enough on the headliner to fit your left arm through and reach in. Remember thee plug that you disconnected from the plastic card holder? You'll be tapping into that wire harness. The wires are taped down to the headliner, you can just peel the tape to one side until you can move the wires, there will be 2 or 3 taped pieces. Once you've done that, you can pull that harness towards the windshield so you can see what you're doing.

This next part is a bit tricky, mainly due to the space you need for your splices. I used simple crimp splices. Look at the mirror harness: pin 8 on the mirror's plug is ground (black), pin-5 is constant voltage (black/red), and pin-6 is voltage when running (black/pink). Before continuing, you'll need to pay attention to TWO things! The first thing is to make sure your mirror harness is long enough to run from the mirror mount, through the slotted hole in the center of the headliner and to the harness to be tapped into. The second thing is to make sure you're tapping into the harness near or on the curved portion of the headliner, checking to ensure the splice-crimps don't interfere with the sunroof motor or headliner when everything is back together. Stagger your splice-crimps to make your life easier. Take the black wire and splice-crimp to the solid black wire you see on the plug. Expose a bit of the black/pink wire and black/red wire from the mirror harness and twist them together. Take these two wires and splice-crimp it to the red wire with black stripe on the sunvisor harness plug.

Now plug in your homelink mirror (hold the mirror, DO NOT dangle the mirror by the harness) and test to make sure you see both the green light (auto dim) and the red light when pressing one of the three remote buttons. Also test to make sure that the mirror auto dims. Once you've tested everything and confirms that things work as they should, disconnect the mirror and put the headliner and trim pieces all back together in reverse order. From there, plug in the homelink mirror and mount it, line up the harness and push in any extra you may have, then connect the plastic mirror trim piece.
