Wiring Harness Options

[D-n-Tyke]

I am debating if I want to try rewire the whole suburban or just piece meal out the bad sections and leave what is working. One factor is the options available for complete replacement harnesses. I was looking at AWW harnesses and they look really nice I only see ones specified for trucks (not a specific one for a suburban). What has eveyone been using? Do you just buy a truck version and then add on to it the addition things included in a suburban?

Love to hear what everyone has done.

GMC Paul’s has underdash and taillight harnesses that are listed as Suburban/panel specific. They also show headlight and gauge feed harnesses as well. I would check them out. I’m sure there are other vendors as well but I have always had great service from them.

I can't answer your question about Suburban wiring but I can tell you that AAW's phone support is top notch. I'd give them a call. I would buy AAW if you can. Great product and support.

If you have any doubts about the tail light harness I recommend replacing it before replacing your headliner. That is if your original headliner is bad. If you are lucky enough to have a nice original then the decision is whether to repair the bad areas or to make and install a replacement harness under the body along the frame. Personally I would go through the work fabricating an under body harness and installing it before I took the risk of damaging unobtainable headliner pieces.
I have seen and inspected both AAW and M&H harnesses. The are both quality products. I have the AAW harness in my Burban (Yes, they make a factory style plug and play harness). My decision to go with AAW had to do with the delivery lead time differences. With pert-near 30k miles I have no regrets with AAW.
But don't get me started on starter switches!
If you do replace the tail light harness harness with an factory style harness I recommend removing the front seat to make it easier to access where the wires drop down from the A pillar.
I am still using the original engine harness, if you can call it original after replacing the ballast wire and converting to a later model SC alternator and wiring head light relays. At the time when I replaced the underdash harness I didn't have a real plan for what I might change in the engine bay. So basically evolution happened and it is what it is now.

It all depends on how involved you want to get into the wiring, but the easiest thing to do is get OEM style harnesses from either M&H or AAW. You can piece meal sections like you're thinking and they'll work with the existing wiring. Also, M&H and AAW both offer OEM harnesses with upgrades too, like wiring for HEI, electric choke, voltmeter, internally regulated alternator, and light relays. And they come all wrapped up, so 100% plug n play.

i just finished wiring the entire truck with Rebel Wires and I know nothing about electricity. It was not hard.
