Homelink Mirror help needed please...

So i might be trading rear view mirrors with a friend who has a 2006(i think) Hyundai Santa Fe because he has a Homelink Auto Dimming Mirror. Now i just need to know 2 things.
1) Is there a module somewhere in his car or is it built into the mirror. Here is a pic of the mirror:

If there is then i guess it would be at the end of the wire going in his headliner which go all the way across the car.

2) There are 4 wire coming from the mirror which plug up to said ^^wires and there are 4 wires coming out from that plug and they go all the way to god knows where... but my question i guess would be what are these 4 wires for? The colours are white w/ black stripe, green, yellow, and orange. Here is a pic:


I guess if there is a second module then i will have to scrap this whole thing because i am going to have to make up a 2 custom brackets for both mirrors to fit each others cars and i was just going to cut the plug with about 4 inches of wire from his car if they are just powers and ground but hopefully there isn't which is why i am asking you guys!!

Thanks!!

 

anyone have any input or ideas? i dont wanna start making brackets if its not gonna work...

 

Ok...nevermind...after trolling through some blogs and forums i found it out on some guys Car Domain for a 96 talon...haha, and whats funnier is some other guy had posted in the comment thanks for listing what wires do what, this is the only place i have found them haha(it is a gentex 346 i found out on the back)

i will let you guys know how the install goes

 

so i dont have to bookmark that stupid car domain...
Yellow - Ground
Black/white - Car On
Orange - Power Constant
Green - Reverse light, When you reverse it will turn off the mirror so you can see while backing up.

 

ill check mine out tomorrow. my truck has that exact mirror in it. Ill let you know exactly where its hooked up.
