I just got a painless wiring harness for my 77 F-150. I started to put it in, first removing all of the other wiring, and I realised what a big job this was going to be. Has anyone else done this before? Do you have any tips for me? I plan to make my own gauge panel, use a D.U.I. HEI style distributor. Everything else will be stock.
Hi Big.
Well, I just finished doing the same thing as what you are attempting except for the fact that I made my own harness. My original dash was replaced with sheet metal and aftermarket gauges and switches. All I had for a reference was a Haynes manual for the truck that had wiring diagrams included. When I tackled this job what I wanted to accomplish was to greatly simplify the wiring and make it easy to troubleshoot when I had to. So, I sat around looking at the book and trying to trace circuits and so on. Finally I just ripped everything out and went at it one circuit at a time. I ended up with one power wire from the solenoid to the new fuse box to supply all the accessories and one wire to the on-off ignition switch and another to the push button to engage the starter solenoid. The only original wiring left is the harness from the solenoid to the alternator and the regulator. I considered getting a Painless kit too but ended up going with switches, breakers, etc that you can get from any automotive store to replace all of the original stuff. It was alot of work alright but the price was right and everything works better than ever.
How much did that kit cost you? My truck is an electrical nightmare and i think every circuit in it has a problem. I was thinking of a painless kit but heard they were pricey.
just received my EZ wiring harness 21 circuits all color coded and named...after a bid of over 400.00 to install decided id try..so far not bad have tail lights and all front lights ran and the engine..tomorropw will go for the biggie inside the cab..i searched a long time and chatted with many rodders from what i got EZ wiring is giving painless a run for the money..mine was $211.00 toal for the harness..quality looks very good..
I'm in the process of installing a 20-circuit EZ2-wire universal harness ($150 shipped) in my 84 Bronco. It's intimidating to look at, but once you read the instructions and lay everything out, it's not hard at all. The wires do not have terminals, and my DAD suggested i get some Hi-temp terminals for the enigine hook-ups, like battery, starter, etc. If anyone knows of a good source for the Hi-temp ends, I'd be grateful.

You can use plain un-insulated ring and fork terminals. You can't get much higher temp than that. If there are some spots where you think you need insulation of the terminal, you could slip a piece of shrink tube on the wire, install the terminal, and then slip the shrink wrap up on the terminal and the wire. I don't know what the temp rating is of the shrink wrap, but I assume it's just as much as the wire.
