Entire 69 dart wiring harness

M&H makes the wiring harnesses that Year One sells (and other places like Classic Industries and Summit). Their harnesses are 100% spot on reproductions of the factory harnesses - same wire colors and tracers, same plugs. They are expensive, but compared to the time or cost of a universal wire system, they are well worth the money. The biggest advantage is that when you are done, you can use the wiring diagrams in the factory service manual to work on electrical problems. You can find the correct part number for your harness on the M&H wiring web site. I have found that the distributors don't always get all the applications right, but you can find your part by using the M&H part number on the disdtributor's web site. One of the big problems with wiring harnesses is the built up resistance in every connection due to slow corrosion. Whatever harness you use, get a tube of dielectric grease and treat every connection - especially the bulkhead connectors.
