So earlier this week I finished the OHC and mirror install. I followed Johns instructions on the OHC and Auto Dim mirror install simultaneously. I found a few variances but worked through all of them and even made a few alterations.
I ordered it on ebay with the harness, sensor and the mirror and ohc. I figured i should get the mirror now or else I would never do it later.
I took the old mirror off and started cutting the headliner. Talk about some nerve racking stuff knowing that at any given moment I could drill through the roof of my truck. Luckily my drill was deep enough that the bit sat down in there and it only stuck out half an inch. So heres the bracket mounted in the roof.
I ran the wires for the dome light and down the pillar. I unscrewed the fuse box and pulled it out and heres what i was working with. A couple of my wires were different colors, but i figured out what everything was with a process of elimination from what I had correct and the help of a test light. I separated the groups of wires by putting the mirror wires on the left and OHC wires on the right. Two wires from the mirror I did a Y connection with the OHC into my power and dimmer. HA...and you can see that crappy thing there is was using for outside temperature!!!
I ran the wires down the rest of the pillar, so i had to make extensions and left them down on the floor.
I then made the relay assmebly for the auto-lamp on the mirror with the two relays I bought at Oriellys.
I connected that to the white/purple wire from the pillar and ran the wires along with my power and dimmer up through the hole behind the fuse box. I cut the four wire and put on connectors there.
I had my efan tapped in to back of the box. I did the same for the power. I also found the dimmer light near the wires where I cut for the relay. I confirmed my finding with a test light. I also modified a wire tap a little with a hack saw, I cut it so it would not tear up the larger factory wire in the truck.
I then wrote where I put those taps in my manual for faster finding later.
Also found the reverse sensor light near the gas pedal.
And heres what you get. I love it and its awesome.
The only problem encounters was the even lowered voltage from the addition of the underdrive pulley a few months ago. And the 11.6 above is actually after the install with everything on in my truck I could think of, I was down to like 10.5 volts when I turned off my truck and only like 10.9 at an idle.So I ordered the 20%overdrive alt from Underdog Perfermance and had it here in two days....hes in TEXAS. And it brought me back to where I should be.
Well thats it. The driving in circles was fun...haha, my girlfriend was with me and she was like WTF. But its looks nice up there and I like the extra map lights.
The only interior mod I have left I want to do is to tackle Johns EATC mod...ha
Thanks to John for the How-tos and writeups and to Wayne with Underdog for the pulleys and fast shipping.
