Looks like you have to build a tent to work in a dry spot. Still bad weather at your place Tahjohns?

 

Haha, yeah pretty much. It was nice yesterday, but I had dinner with family for my birthday after work. It is supposed to rain today and tomorrow. It is supposed to be nice this weekend and I will be out of town. So we'll see.

 

Ah, another JUNE guy!

Good luck then for another year.

 

Thanks. It didn't rain yesterday but I just didn't feel like working on it. It is really nice outside right now but we will see what it is like when I get home tonight.

 

I made some progress yesterday and also acquired some confusion.


Here is the progress I made.




Here is where I am confused. The 4 pairs of wires that match, don't really make much sense. The 2 green ones are especially confusing. With the car in reverse, only one coming from the firewall has power. However, when you send power to either one going to the rear of the car, the backup lights will come on. One of the orange ones and one of the black with white stripes have 12v with the key on, but I don't know where they go. I forget about the 2 blue ones. The good news is that I can turn the key on without smoke. So progress, right?

 

One thing to keep in mind is that the trailer wiring duplicates the main truck wiring heading to the back of the truck using the same wire colors and will not energize anything heading to the back but will be hot from the fuse block when that function is energized.

Where in the truck did this corrosion/breaks occur? I need to see where we are in reference to the cable splices.

It was under the carpet in front of the driver's seat about 6" from the brake pedal.

 

Orange is used often for power but the only power I can find that goes to the back of the truck are always on, not switched with the ignition: rear wiper motor, courtesy lamps, seat lumbar motors.

The only black/white stripe wires I can find is the signal for the rear hatch release and suplimental restraint gnd but those should not get power from ignition on.

There are a lot of blue wires:

Dk Blue/white: rear door jam switch

Dk blue: rear window motors, seat front vert motor, lumbar

Lt blue: high mount stop lamp, seat rear vert motor, seat recl motor

and greens:

Lt green: back up lights, drivers seat hor motor, drivers seat recl motor

Dk green: rear wiper signal, driver seat vert motor

You should have two lt greens from the firewall getting power when the truck is in reverse, the main back up light power and the trailer back up light power. You can pull the trailer backup fuse to find the main one. That gets connected to the single back up light lt green which you can find with a continuity meter from the rev lights to your options at the splice.

In general you can verify the load side wires (heading to the back) by using a continuity meter from the load back to the open wire at the break. You can verify the signal or power from the firewall by energizing that function or pulling the power fuse and rechecking.

Wondering if a couple of those could be for the security/alarm system?

 

Thanks guys. I was away all weekend, but I work on this a bit tonight. I think what I may do is remove the seats and the carpet so I can follow the wires back further. I also want to lay the carpet out in the sun to dry. I need to replace the driver's door pins, hopefully that stops the water leak. That was the case with the passenger side.
