66 wiring

I just ordered a wiring diagram for my 66 f100 stepside. I am having problem with my taillight I isolated the problem to behind the dash to my surprise when they installed a newer steering wheel the wiring was less than professional hell a monky could have done a better job after investigating this rats nest my truck will not start it turns over but thats it so now I have to make sense of all this. **** me off when someone does a job halfass.
Good news I figured it out it now starts now onto the original problem

First and foremost, welcome to the Family of Ford truck Enthusiast!! Unfortunately, you are stuck with your signature 'stepside' which chevy owner use to describe the Ford 'Flareside' pickup bed; consequently, likely open to some harrassment and criticism from a few fellow members. Think you will find this forum a warehouse of information concerning your classic treasure with knowledgible and helpful members.

The Ford wiring manual will be invaluable in tracking down the electrical gremlins. Majority of the time found the problem was due to a faulty ground. Had a simular issue with hafass workmanship with the 65 with the 390, prior owner used his imagination when it came to installing various add on accessories. Ended up tearing out all the add on's and starting from scratch then adding couple additional ground straps in critical locations; especially with the CC chrome plastic dash. Anyhow, again welcome to FTE.

No matter what you do, you're still dealing with 45 year old wiring. If keeping things original is not an important factor in your life, there are many companies offering wiring kits that will work. I have a 66 Stepside and stripped out all of the old wiring, replacing wuith a kit from American Autowire. It was not a direct replacement, but with the diagrams and instructions included with the kit, it was easy. In addition, I now have things like a fan relay, headlight relays, emergency flashers, and circuits for any add-ons I might crave in the future. By the time you're finished, you'll probably spend as much time and money fixing the old stuff as you would have replacing it. And, you'll STILL have 45 year old wiring.

In addition to aftermarket kits DPillips mentioned there are reproduction harnesses with same wire color codes and connectors. Replaced all the harnesses on the 65, matter of unplugging the old and plugging in the new. Cost of harnesses vary runnning from $100 ea. for the taillight and headlight harness, and if recall the alternator/regulator harness ran around $50. Unfortunately, have not found anyone who reproduces the dash harness; although, reconditioned, and repaired damaged wires and added couple circuits on the dash harness in the 65 and just used a heck of alot of plastic ties to keep the spagjetti together until harness wrap applied. For info purposes, suggest never using the electricians tape in rewrapping the harness circuits, there is a specific wrapping tape for harnesses, it's non addhesive and not a pain in the backside to rewrap or add circuits.
