Hello,

So one of my shortlist goals for my 48' 1/2 ton is to just replace all wiring but keep 6 volt system.

I'm shopping for harnesses specific to the truck, and I've come across a lot of variation in prices.

Has anyone actually installed this harness from Classic-Parts, and if so, how were the instructions and labeling for you?

I guess the only extra lighting I'm looking to do, is run a wire to the original spot-light on drivers side. Everything else stock and no radio.

Thanks Steve

I installed one about 6 months ago. The instructions do leave a few things for figuring out. It's basically a "wire by number", but not all the wire numbers are in the instructions. You can figure it out by using some basic deduction, but it can be a little frustrating. In the end it took me only a day and everything turned out great. I would recommend that harness personally based on the low cost and end result.

Don't forget, if one gets a 12 volt harness it will work fine on a 12 volt system, however, a 6 volt system requires thicker wires, so beware.
