Wiring Harness Options - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm looking to put a 5.3 and 4L60E into my '69 GMC - the factory wiring in it is junk as to be expected. I've heard rumors of a single harness to run the 5.3 with accessories that also replaces the wiring that a GM harness wouldn't cover such as lights... anyone else heard of this type of harness? what's your preferred harness and why?

I used the stand alone to run the engine and all the senors for it.
The rest is the truck wiring.

It sucks not being able to hear! LWB trucks rule, if you don't think so measure your SWB! After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
