Need a Wiring diagram 72 Barracuda

[sheetmetaldan]

Can anyone point me to a good wiring diagram for my 72 Barracuda? Specifically the gauge cluster. I had someone put in a new painless fuse block but they never got the gauges right none of them are working. They were all working prior to this so I know they are all good. I’ll just fix them myself at this point. Thanks

Oh, that's pretty handy. I didn't even click on the link to see what it was before I posted my comment. I'll look before opening my mouth next time.

Your "Painful" kit should have had directions for connecting their wiring to your dash. Basically, all you need is gauge power, and the sender wire for temp, oil and fuel. Don't forget to make sure you have a good ground to the dash or nothing will work correctly. Is this a ralley dash?

Non rally dash. I had my mechanic do the work. I’ll take care of the rest myself at this point.

Just noticed the “painful” in your post you are so correct!

Finally dove into my wiring issues & discovered the “mechanic” cut the wires off of my dinner switch & a wire to the headlight switch! I had all this working before I too it to him! On the plus side he never charged me for the work! I kept asking how much do I owe you? He was always saying he had to figure out the time his guy had on it. Think I’ll stop asking what I owe him….
I did the work myself at least 10 years ago now I gotta figure it out again!

I’ll bring my modern vehicles to him but my Barracuda is never going back to him!

While you on that. Maybe time for a headlight relay circuit.

Just in case you need the rest of it now.

Glad to see you found the issues. Also, great diagrams RTA. I wire old vehicles every week and have seen more than my share of poor-quality work. Usually harder to find and fix what someone else screwed up. Not sure what the guy was thinking just cutting the wires. I was able to just make a few minor repairs on the harness on my Challenger. You are better off just doing it yourself. I can just build my own harnesses, but anyone that has to buy should go with American Auto Wire or Ron Francis. I've even seen some cheap import kits that are better than Painful.
