Aftermarket wiring harness

[79bonanza]

So I have my main K5 build going on and on the slow back burner my Crew cab and they both need just all new wiring harnesses. I thought I'd be able to save the K5 wiring harness but it's just old and too brittle to not worry about later on.
And the crew cab is just a mess, full emissions/choo choo customs all the weird accessories and just bare wires going to nothing.

I've been doing some research and I've been looking at the Painless wiring harness and the Ron Francis wiring harness. They run about the same price but the Ron Francis just looks alittle cleaner.

I was wondering if anyone has any experience with either manufacturers product or any advice where I can get the oem connectors for like head lights tail light etc...

I have the painless kit in my 71 c10 and I loved it. Lots of extra wire that's labeled every foot.

you should call Painless to make sure they sell a harness for your crew cab. Much of Painless GM wiring harnesses are for Camaros and 1/2 ton trucks with a 700R trans...1-tons, not so much. Howell fuel injection makes a wiring harnesses for 1-tons. they cost a little more, but that is because they are the only game in town for the more rare 1-ton truck.

Oh good call, I'll check them out and see if they offer any crew cab stuff

Hey I've looked over the Howell website and I can't find anything besides engine swap harnesses

they have the TBI to ECM harness, but not the ALT, starter, or head lights part of the harness. You may have to splice in half of the Howell harness into another aftermarket harness. This is a crappy fact I found out when researching a new engine harness for my 1991 V3500. I do not know what year, engine, and trans you got in your truck, but my one-off year truck is a complete oddity to find any parts for. After the assembly line completed the run of my 1991 V3500 trucks, they through-out in the dumpster, all documentation the engineers created for the assembly line workers to use.
