I installed the 69/70 Mustang harness into my 1970 Mustang fastback. I have to say that Painless Performance really got this harness right. The harness went in easily and fit better then the OEM harness. They provided plenty of fasteners and connectors to easily complete the entire installation. I really thought this was going to be a PAINFULL experience but to my surprise it was not!! The new harness provided for additional circuits and has incorporated into it for more modern technologies. I also installed an MSD, Mallory Unilight and OEM HOOD TACH which required additional wiring to get everything working. Along with the well written manual, their Tech support was able to help me with the additional connections. My old harness was a fire waiting to happen. I had circuit that did not work due to shorts and frayed and cracked insulation requiring me to tape everything which made the harness look horrible. I also added the wire cover for looks and wire protection. The car runs great and the harness is performing perfectly. I am so glad I decided to replace my old harness with a PAINLESS!!!

Not only are PowerBraid & ClassicBraid great for wires, but they also can be used around hoses, lines and other items throughout a build.
