I recently installed an ez wire harness in my 1977 F-250 to replace the factory harness and I've got most everything working. I printed out the wiring diagram from autozone and most of it was correct until I got to the gauge cluster. Then nothing really matched and I need some help. If anyone has a correct diagram, something scribbled on paper I'd like to see it. All I really want to work are the turn signal lights, high beam indicator, fuel gauge and the gauge lights too. I'm going to run aftermarket oil, temp and amp guages. Any help would be greatly appreciated.
PS I have gauges and not idiot lights.

Your Replacement harness probably is for the cluster without guages. I don't think the cluster with guages's pig tail plug is as wide as the one without gauges. If originallity isn't a concern you could swap in a cluster with idiot lights, or you could get a factory wiring diagram like the ones you find in a chilton manual, and splice on the correct pigtail to plug into your current instrument cluster. Or, of course, I suppose you could order, or pull a harness of a junk truck for your specific application.
The ez wiring harness is universal unless you are putting it into a chevy, then it has the plugs you need. I had to try and decipher which wire from the factory ford pigtail does what and that is what I'm still working on. I'll see if I can get a hold of a chiltons or haynes manual. Thanks I hadn't thought to check those.
By the way originality is of no concern, I have a cummins motor and an nv4500 transmission mounted and wired up in this truck. It is the truck of my dreams. I just want everything to be functional.
