Wiring harness

The most common area for the power to fail is in the flex area from the pillar to the door. Not hard to repair, remove the inner door trim, then the lower kick panel. You will find a connector at one end or the the with the door wiring. Just follow the wires through the flex and repair the broken ones.

I tried that it does not power on. i fixed some of it, but I cannot find the diagram to double check the wiring.

OK, here are the locks and windows. Yellow is the primary power for the windows, Orange for the locks. Both use simple polarity reversal in the switches to move the actuators.

I finished the harness thank u Steve now I got another question I got this black and white wire that is in the convenience center I have no clue what is goes to I'm stumped

Black/White is a ground wire. Images show what uses that color. If I'm correct that is connector 210 a cross body harness. The wire is in position A The problem is that none of the diagrams show where the wires actually go !!!

I thought it was a 4wd indicator wire? My truck ain't starting because of the wire I think

The items in those diagrams are the only ones that use the black/white wire as a ground. 4WD indicator wire is one of them, but not the only one. What does the truck do in terms of not starting?

Just click I tested the starter and it works

OK if it's just a click you want to check the battery for a good charge, then check the battery cables themselves. GM side terminals are very bad for corroding inside the rubber around the terminal ends. Because of the way they mount any acid that manages to leak past the battery seals wicks into the actual cable. I've had cables that look brand new that were actually eaten apart inside. Next check that the other end of the cables are clean and tight. Check the start relay and the socket, a weak terminal in the socket could cause low current flow so the starter doesn't engage.

Ok everything is done except the dome light the other interior lights come on i got both door jambs disconnected will that have the dome light not to work

Yep. The courtesy light routes the ground through the door switches.

Also will them doors switches make my cargo light not work and same with the third brake light

Sounds like the cargo/CHMSL has a different problem. The cargo light may turn on with the dome light if the switch is turned on. But the CHMSL won't it gets a feed from the brake lights.

Ok because I got brake lights at the bottom but not the third

Factory just taps the same light feed for the CHMSL on that year.

What do you mean taps

It is spliced into the same wire that feeds the brake lights. The wire comes from the brake switch up to the splice. At the splice it goes to the multi-function switch, the BCM, the ECM and the CHMSL light.

Oh I understand now thank u I will check it out tomorrow morning I will let u no

Ok I got another question everyone I push the brake pedal the brake fuse keeps blowing??

Short in the wiring, maybe why the CHMSL doesn't work as well. This is the wiring for the exterior lights. Might help.

Ok so I tested the white wire for the third brake light and the test light lit up when I was holding in and it went off as soon as I let go of the pedal

What do you think

Did you forget about me

Been busy getting stuff ready for the 4th. Polishing fire equipment and mounting flags.

Anyway, I would say you have a short somewhere if it is blowing the fuse every time. Also check the ground for the light, if the ground is bad you don't get a light.
