Yep, I'm a newbie here and I'm kinda stuck. I bought the girlfriend a sharp '91 F150 4x4 XLT Lariat full load short box regular cab for her birthday. Nicely set-up with the 5.8, auto in Dark Shadow Blue Metallic and she really likes it, if I can I'll get a pic of it up here.
But here's my problem, she likes the Gentex mirror that's in our Jeep Rubicon and she asked if I could install the same mirror in her truck. I run an auto glass company so it's not a big deal or so I thought. I went down to the jeep wrecker grabbed a mirror installed it, now we have a compass temperature display, auto dimming mirror with map lights. I've got it all working fine but I'm looking for the reverse positive trigger under the dash. Once hooked up when you shift it into reverse, if the mirror is dimmed due to bright lights, it'll automatically cancel that feature and un-dim the mirror so you can see where your backing up. Once it's shifted out of reverse it will go back to it's normal operation.
But for some reason I can't seem to see that wire....anybody got a wiring diagram and can see which wire I'm looking for?

 

Anyone?

 

Impatient are we?

 

This should help

 

Hey Sylver91 thanks alot, that does help. My girlfriend is out of town for her work and so I've been staying after work trying to get this done along with a few other things. I took out her crappy old deck and put a new one in with blue tooth, pandora and a bunch of other stuff. I took out the bench seat (to add a huge Alpine amp) and had it re-inforced as one of the previous owners was a big guy and demolished it. After driving it for an hour you'd go to get out of it and it was like climbing out of a hole. While I was at it I added some new kicker 6 1/2 door speakers with tweeters in the kick panels and shampoo'd the carpet and installed a new set of Lloyd's F150 logo mats that I got off of eBay.
I also installed a set of lock actuators I got from Rock Auto for 85 bucks. They arrived at the U.S. postal box and they were OEM!
I also redid the rear brakes and replaced the parking brake mechanism with a used one and installed new parking brake cables. While I was at it I hard wired her GPS unit for her so she can charge her phone or I-pad if needed. I also changed the windshield and coated it with aqaupel and painted the arms and put some new blades on it too. And here she thinks I just installed her mirror, lol. So she's coming into the airport tomorrow and I have to get it back together tonight and return it to the Airport parking lot asap.
This week all I've lived on is coffee, donuts, beer and pizza.

Again thanks! It what I was looking for...

 

Jeez with all that work you got done, wanna come do mine next ?
