Wiring Harness Options
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. |

Re: Wiring Harness Options
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.

Re: Wiring Harness Options
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.

Re: Wiring Harness Options
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.

Re: Wiring Harness Options
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.
