Anybody built their own harness?

I just installed a new harness in the 69 mustang a couple of months ago. I had originally planned on one of the direct fit AAW or painless harnesses ( have the painless in my 69 C-10 installed 25 yrs ago) but couldn’t swallow the near $1000 price tag now. I did a little research and found Kwik Wire.

I bought one of the 22 circuit kits during a Labor Day sale that cost 1/3 of the Painless and AAW. I have to say I was VERY impressed with the product. Sometimes installing one of these aftermarket GM based harnesses in a Ford has a lot of research to do to make it work. The instruction book they send is very impressive, it’s a spiral bound notebook that goes into detail on every possible application for all manufacturers. The pages in the book are heavy gloss paper with color diagrams which will be a very valuable resource for reference on future projects. Also, on the whole harness, I only had to lengthen one wire, they provide plenty of length. I also removed all of the OEM connectors from the original accessories and changed everything to weatherpack to make for an installation without a bunch of OEM rubber bullet connectors butt connected onto new wiring.
I have installed harnesses for 30 years from all different manufacturers and have to say this one has been the most impressive company I have dealt with.

Sounds like a good way to go! I once installed an inexpensive EZ Wire universal kit, which used nice components, but the documentation was laughable, along with their tech support.

Just noticed the AAW #510089 67-72 kit costs $764 at Summit Racing. I bought mine in 2021 for $575, and thought that was expensive! Today I might actually use a less expensive universal kit, because even the 67-72 kit needed some fabrication, like changing out the kit's steering column connector and terminals. And I usually do some custom work on the charging circuit.

I got my direct fit painless for $250, but had wholesale connections and it was 25 yrs ago.
Here’s a couple examples from the spiral bound notebook showing all the various different charging system hookups. I too did a lot of modifications, such as hard wiring in relays for the H-4 headlights instead of using one of the adapter harnesses. I’m very OCD about wiring…
