Chassis/frame wiring harness

I can post the connectors with the wire colors and functions, but this is likely going to be frustrating on your part because it is going to take some time for me to get it right. The first thing to do is visit a number of salvage yards where you pull your own parts. Do a search for "Pull-A-Part" and see if they have any yards near you. You can also do an inventory search to see which ones have trucks like yours, but be aware, they can't tell you colors or options a vehicle came with, or what has been removed or damaged by other people. Wire harnesses aren't a popular item, so if you find the right model, you'll likely find a good wiring harness.

Also be aware you may find harness that will work, but it has a totally different part number. One could have all the right wires, but the assembly is a foot or two longer for a longer truck. The salvage yard harness could have a few extra wires for an option not on your truck. There's no harm in having those extra wires in the harness.

Where I would try to draw the line is at finding a harness from a different year. If you have the dealer look up two part numbers for the same harness for the different years, and they are the same, that will tell you the plugs are the same, and a harness from the different year might work, but you still need to check that each wire is in the same locations, even if the color is different.

The last resort is buying a new harness from the dealer, if it is even available yet. They are hand-assembled, so they're horribly expensive.

If you find a harness that is close to yours but is missing a few wires, those can be added separately. To get the needed terminals, the dealer will have kits for the different years and models, so you can buy just what you need. I prefer to snip the connectors off at the salvage yard, with a few inches of wire. That way I just pull out the terminals I need, and splice the wires together.

Those connectors are going to have some type of locking wedge that must be pried out, then you can use a pick or special tool to bend the retaining finger, allowing you to pull the terminal out by tugging on the wire.

For the connector pin-outs themselves, tell me exactly which connectors you need and where they're located on the truck. Use these charts as a guide. Those that have a blue box around the number have drawings to show where they're located.

Thanks. I found a place that is supposed to have a replacement bundle. I am thinking it would be best for me to go that route.
Thank you for your help.

Please keep me updated on your progress.
