Howdy, I've used a Painless 18 circuit harness, with provisions for the later model, tilt, GM steering column that's installed, for my 1964 Carryall... The quality is excellent, was very easy, just tedious, to install... Any harness is tedious... All wires are clearly marked throughout its length...
I'd say the Painless harness was worthwhile, even though expensive, since tech responses were very fast and helpful...
Everything worked and I have pre-labeled circuits if I chose to add options...
Summit Racing had the best prices when I bought mine... hope this helps...
Later
