Wiring Help - Homelink

I finally got around to installing my Homelink and can't get it to power up. I readily admit I know next to nothing about electrical stuff but I thought I would give it a shot.

Three wires; ground, switched, constant 12V. I terminated the switched & constant 12V to the fuse box using add a circuits w/ 5 AMP fuses. I followed a previous post regarding what circuits are switched versus always on. I terminated the ground behind the driver side foot panel to a bolt that had what looked to be other leads grounded to it (I also followed the advice of a previous post for that).

When I start the FJ, I am getting no lights on the Homelink; dead. A few questions:

1. I am not certain about the ground. The bolt has paint behind it, I would think it should be bare. Is there another location for a better ground?

2. The add a circuit can accomodate two fuses. One is intended for the circuit it is replacing and one for the new fuse. I only have one fuse in each since I tapped into a vacant location. Do I need a fuse in both slots of the add a circuit?

Any other suggestions on what I am doing wrong?

I know I should get a volt meter and start checking for a good ground and validate I have battery but this is where my electrical stupidity kicks in.

Thanks in advance.

voltmeter is the way to go. You can check whether or not your getting 12 volts off of the "add-a fuse" and whether the bolt is providing a ground.

Re: Wiring Help - Homelink

The add a circuits take two fuses--double check me by reading the fine print on the package but I remember mine needing two to operate.

Hope this helps.

That was it. Like I said, I am an electrical idiot. Everything is operating.

Thanks for your help. Hope I can return the favor someday.

Re: Wiring Help - Homelink

I bought the Gentex Homelink mirror with auto dimming. I did not get the temp & compass option since the FJ already has it. I think I paid $219 plus shipping (I believe it is actually manufactured by MITO Corp.).

No pics during installation but I'll take some tomorrow of the final install. I was pleased with how it turned out. I followed previous posts for removing the A pillar trim, driver kick panel for the ground bolt, and fuse box locations for switched and constant power. All posted instructions were spot on and very helpful.

The only thing you really have to deal with is the old mirror. I removed the old mirror, cut the old mirror & arm off so the only thing left was the small metal mounting plate. I screwed that back into the headliner and snapped the black factory cover back on it so all you see is the small black cover.; doesn't look bad.

If you want to discuss further, feel free to email me; jway1@tampabay.rr.com

Re: Wiring Help - Homelink

Attached are some pics (first time posting pics so I hope it works).

I got my FJ about a week ago. I was supposed to get a TT but the deal fell through (something about not bringing a car in from outside of SE Toyota). So they built this one the way I wanted it at the port in Jacksonville. I have been very pleased with it.

Re: Wiring Help - Homelink

Nice looking FJ, and I like the mirror install, does it tuck under the headliner.

Yes, the wiring harness tucks under the headliner and runs down behind the a pillar trim piece; all hidden. I also purchased the black plastic piece you see above the mirror that hides the wiring hareness from the mirror to the headliner. It just snaps in place.

I'm a day late but for anyone else here is a good write up on installing a Gentex mirror.
