HELP! Aftermarket wiring harness (2 Viewers)

[SHAUNBLACKMON]

going to pull the trigger this week on a new wiring harness, old one in 74 is just too "hodgepodge". It seems like everyone is selling the same one, but for different $$$ (250-350). Anyone know if one is as good as another??? JEGS seems to have best price on a universal one. 264.59,,,, HELP!

Buy one from @Coolerman

Or send yours in for a full rebuild.

Cooler man is not taking any more orders for 2019,,,

Nothing painless about that crap harness... go with oem replacement or repair. Worth every extra penny... the painful harness route ends up costing more getting it hacked up enough to use...

Damn.


In reality they’re not to insanely hard to fix, pull it out, tack it to a piece of plywood, and solder all your connections, then heat shrink.

There’s a schematic thread floating around here somewhere.


I rebuilt mine a couple of years ago.

If coolerman is done, you’re still better off pinning your harness to a piece of plywood and fixing it one wire at a time

Do you guys unwrap the old tape and rewrap with new (non-adhesive stuff)?

 

[LAMBCRUSHER]

Yeah.. or even use zip ties every few inches and then get some loom wrap from the likes of McMaster Carr. I use their hook and loop fastened braided heat resistant loom wrap. Makes building and future access a breeze.

I’ve got shorts blowing fuses and random partially unconnected wires as well as spliced, was going to do aftermarket and leave existing in place as much as I can till new is installed

Will probably go after market, so I can drive it, then based on mine rebuild or repair. Might even use it as a template for custom builds

Aftermarket is kind of a pain especially surrounding brake/hazard/turn signals. The original harness that we installed had been on fire and was refurbished. While Coolerman doesn’t have time to rebuild yours, he will sell parts and provide valuable tech for you to rebuild it. If you take it step by step and slowly eliminate all of the POs WTF and then repair your problem areas you will have a better end result than trying to adapt the Generic harness into your truck.

The quest for instant satisfaction will always end in expense , compromise and frustration. Good luck

I've just bought the painless 10202. It's their fairly generic harness. I disagree with a lot's that been said (other than Coolerman is a huge help and not taking any more orders for 2019). My rig had seen so many changes, there's no harness that would go right in. Painless makes the harness you see on a lot of the sites, and the prices are down right now - but still $350. I'm doing the whole 'lay it out on a board' thing right now to get all the changes to the harness sorted before it goes in.

Yes, you can re-warp with regular electrical tape, or get some braid - painless sells a kit for that too.

Haven't been able to source the connectors and Coolerman posted that he does not have the '77 connectors to do the harness anyway. I have done several aircraft harnesses but am wondering about sourcing the wire in the different colors w/stripes as required on the wiring diagram. Brain is only working at 10% as I have the flu right now. I bought a 1,000' reel of white/black 16 ga. ground wire from Fastenal (smallest quantity I could buy) Price was about .17 cents per foot and I will be willing to sell some if it as I only wanted about 150 feet.

On my 77 I did what others posted. I pinned it to a sheet of plywood. I unwrapped several inches back on most connectors to make sure the wires were good, and replaced everything that looked questionable with new, correct wires and connectors from coolerman. Well worth the time and effort. I know it sounds hard, but I promise it will be easier than retrofitting a generic harness. Rewrapped harness with non sticky black electrical harness tape. If you dont have time to do it right, when are you going to find time to do it again.

This.

All the way!

I am by no means an expert. My buddy who did my custom harness used weatherpack connectors, along with a ton of other way overbuilt items. If the OEM connectors aren't available it's an option!

Same here. Just about every connector you’ll need can be purchased from Coolerman, along with wire, harness tape, etc. This way everything is terminated at the right place, right length, etc. I also added some wires for an aux. panel while it was unwrapped.
