Calling All Electrical/OHC guru's!!!!
Well this past Sat. I got an OHC/Auto-Dim Mirror/Lighted Visors out of an Explorer. When I had just the 2 wires ran to the dome light the OHC worked the way it should. Map lights cut on when the dome light was on, and you could cut them on and off as you please. The only thing I thought was a lil strange was that the display would come on when the dome light was on.
Now on Sunday I decided to finish wiring up everything except the temp sensor. I ran the Gray/Black wire to the Gray/Black wire on the GEM, the Lt.Blue/Red to the Lt.Blue/Red on the radio harness, Gray/Yellow to the Yellow/Black on the radio harness.
So now I am thinking great I'm done. The hardest part was cutting the headliner. Wrong, this is where it gets good. When I cut the truck on the map lights on the OHC and dome light stay on like a door is open. The cargo lights stay on with the door closed but when you open the door they shut off.
What I have come to find out is:
If the Gray/Yellow wire is not hook up I have no problem with the Map/Dome/Cargo lights. But obviously no power to the display of the OHC when the dome light shuts off.
If the BLK/BLU wire is hooked up:
Truck On: Map Lights work like they are suppose to. Cargo lights cut on when the door is shut and cut off when the door is open
Truck Off: When the door is shut the OHC has no power. When the door is open the map lights cut on and the screen comes on. Also the door chime is going off when the door is open like the key is in the acc/on position. But if I unhook the GRY/YEL the door chime stops.
If the GRN/ORG wire is hooked up:
Truck On: The map lights stay on the OHC but the cargo lights work fine.
Truck Off: The map lights work.
Any help is appreciated. If worst comes to worst I will just leave the OHC unplugged from the dome light, and just run the Green/Orange wire to the visors.

Something is crossed somewhere, either in the console installation or some other mod. I would first try it with any other possibly related mods disabled - this might include lighted visors, autodim/autolamps mirror, dome light swap, etc. Then recheck the console wiring as follows:
Tap the black/light blue of the overhead console into the black/light blue that goes to the factory Ranger dome connector.
Tap the light green/orange wires of the sunvisors and overhead console into the light green/orange that goes to the factory Ranger dome connector.
The dimmer wire of the overhead console is either red/black or light blue/red depending on the year. Tap it into the light blue/red of the ranger's radio harness.
The overhead console power wire is gray/yellow. Many how-to's tell you tap it into the yellow/black of the radio harness. That's OK unless you are also going to install the autolamp mirror. In that case, it is better to tap the gray/yellow of the console and the red/yellow of the mirror into the Ranger's gray/yellow - it can be found at several places but the easiest is probably at the heat/AC control panel. This change will keep the autolamps from turning on the headlights needlessly after dark when the ignition key in the ACCESSORY position.
Blue/white and blue/yellow to the same on the ambient temp sensor.
Gray/black tapped to the gray/black of the GEM.
Black to chassis ground.

I have removed the dome light and installed the screws of the dome light into the connectors and then the 2 wires directly to the screws and the problems still happen. So I think the dome light is ruled out.
Thursday is my next day off and I plan on pulling the headliner to check all of my wires. I know that I have my dimmer wire right because I checked it and the display dimmed like it should. After I look at all the wiring I will report what I find.
I now have it FIXED
My problem was when I ran the harness across the headliner and down the drivers side a-pillar. After having everything together I reinstalled the visors and the bottom inside screw went right through the middle of the harness. It took off just enough of the insulation of what looks like the gray/yellow and black/blue wires to cause the problems. All of this just because my harness moved up 1/2".
Thanks you two for the help. If nether one of you posted I wouldn't have figured this out til Thursday.

Yea, found it all by luck. I was just going to start taking things apart to drop the headliner sence the dog woke me up at noon and I couldn't go back to sleep. As soon as I dropped the driver side visor I saw where the screw went through and thought "crap I wonder if that's it?" Pulled the wires apart so they wouldn't touch hooked the battery up and BINGO it worked perfect.
