So I was sick of my ugly, bad stock rear view mirror and decided it was time to figure out the wiring and order an OEM auto-dimming rear view.
Had a third gen mirror in my cart on eBay for like $35, with part of the pigtail, and ended up coming across a 4th gen mirror for under $30. Seller told me it did NOT have any of the harness which was a bummer, but I found one for $16 with about 12" of wiring. Ordered both, mirror got here the next day (Came from my state) and behold, there is wiring with it. I was mad. Hopefully the seller will let me return the harness I bought.
Oh well, but I got it installed easily, tapped into the compass modules wiring, but did it over in the A-Pillar. Tied the wiring into the loom that already ran down, and it looks OEM as can be! I opted to not wire the reverse circuit (12v when in reverse) which just disables the dimming feature while your car is in reverse. I rarely use that mirror when backing up anyways.
So much better! And it looks better as well.
Cheap, crappy, wimpy looking stock mirror: (Wiring was hanging down as I already started the project)
Nice looking OEM power mirror:
Wouldn't ever know it wasnt stock:
So a little backstory before my next story: I noticed some aftermarket wiring under my drivers footwell area which looked identical to maybe a lower end remote start or alarm. I assumed it was just removed, or something because I didnt see any modules down there, never really looked into it.
So I was ordering LEDs for my gauges, climate controls, and rear climate controls. Was going to check the bulbs in my vanitys, but I NEVER use them, so that'll come at a later date. While I was out there double checking my bulb count, (I still have my center bezel off, working on fitting the EQ into it), I see these two dim LED lights way back in the center flashing.
Reach behind it from under the steering wheel and grab what I think to be what was flashing (it was) and it was this little box module tied into those wires I mentioned above. The module it probably 2.5" by 2" and maybe an inch tall. Clearly not anything related to remote starting or alarms.
I unplugged it and brought it inside to do some googling, its a GPS tracking device with remote ignition disabling available. Only available for sale to companies it seems like. Im going out on a limb and assuming its the dealer I bought it from, in case you don't pay your note. Upon some more digging, I found mine is only wired for power so theres no ignition disabling but what an odd find!
