is there another way to do the connectors at the fire wall other than the stock configuration, i want to totally rewire the entire under hood of the truck but i cannot find a decent donor truck with wiring to do so, i can make improvised connectors for the ecm, voltage regulator, and other connections, but am having problems getting it all through the fire wall, any suggestions are appreciated, or any one wanting to donate a wiring harness is welcome to do so, as long as it is free + shipping= shipping cost.

my harness is shot i have rebuilt it but after several fires and going bald pulling my hair out i just want to do a better set up then what is there with all new wire (all new) and i thought about using a 75amp bridge and mouning it inside of a house breaker box, that would water proof it and then run the wires through the fire wall and use standard line connectors there that way i can get to everything.or i just need a better oem wiring harness

You can send your harnesses to Painless wiring and they can redo you an all new harness to factory specs, or if you want a fully custom wiring harness, check into the Summit catalogs.

If you have a Radio Shack near you, give them a try. I've always found interesting things for wiring there including Multi-pin connectors, etc.

If you don't have a Radio Shack, you can also try wiring parts for big rigs, thru dealerships for Peterbilt, Kenworth, Freightliner, International, etc. Many of these big rigs are put together with sometimes very simple wiring along with external turn signal switches, toggle switchs, etc.

Unfortunately, I found this in their FAQ..

*Do we custom build harnesses? Not on a single-harness basis. We have a variety of universal harnesses in stock that can fit almost anything. Call us and we can tell you which one we recommend. If you were to need a quantity of harnesses, you can contact us to submit your sample design and we can do a quotation for you.
One of their universals are nice for the basic circuits, but if you have a computer, you are SOL...You'd have to pull the whole OEM harness apart and strip out all the computer and TBI/MPFI wiring.

when i rewired my truck, i just put a hole in the fire wall and ran flex tube thru it and all my own wires. i kept the old connector on the wall and kept the wires running to the lights and wipers. sounds like you re on the right path.
have fun. lol

Sig, if the old harnesses are still in some sort of rebuildable shape, save them and send them to me...I'll pay the shipping.:)

Hey Aaron, I took a look at my truck today and your starter relay is wired up different then what i got. I'll try and get a pic for you. That might have something to do with the fire

In the mid to late 70's trucks equipped with a manual transmission used a different relay like the one below. It gets its ground through the case instead of a neutral safety switch. He can use one from an automatic but would have to hard wire a ground to the "G" terminal on the relay. As you can see there is no "G" terminal on the Manual tranny relay in the picture below.
