Does the Home link buttons on some of the visors on the Mark have some kind of module located in some other place for it to work?

I'm bumping this because I have the same question. Can you install a Homelink visor in a car not originally equipped with it, and have use of its functions?

It should work fine but you will need the ones with the little home on them to work with newer garage door openers with rolling codes

The homelink module is in the visor itself. As long as the connections fit, it should work. With newer garage door openers, it will have to be in the learn mode to capture the program. I still haven't been able to get my CE to program to my Chamberlain.

sure enough.
i have one in my 93. i believe its from a 2nd gen.
the wiring change is super easy. a connector change and ground it to the mounting screw.

If I recall correctly, normal visors have a connector with 1 pin, right? A home link has 2 pins, power and ground? Thanks!

I put one in my 97 that didn't come as original equipment.

You've got to be super careful prying the visor open like a clamshell.

There's a rectangle that you'll have to cut out that was molded into it from the factory, and then you just splice it into the existing wires that are there for the vanity light. All it needs is the 12v power and a ground. You'll also need to cut 3 small holes in the fabric of the visor, for the 3 buttons. Don't cut them too big, or in the wrong spot, or else they'll be visible when completed.

I did this about 3 years ago, and didn't have a camera at the time, so no pictures.

I had an extra Homelink visor (wrong color for my car) that I had gotten at the junkyard, so I took that one apart first, to make sure I didn't mess up my black one. It was a big help.

They have the same connectors. All of the visors had 12v power and ground, for the vanity light.
