Harness in bad condition

[Manu Mach1]

Hello my friends,

A mess, yes it's a mess. And what I hate is when someone cut wires on original harness. I would like to clear things but first I need to know what is what.

This one is ok but not connected to anything, with 12V after contact.



This one not connected with broken wires. I guess was for radio with 12V permanent?



Those 2 with no power at all, left into the glove box.



Look at this!!!



I had a look to the '73 wire diagram, but for me it's like chinese.

Thanks for your help,

Manu

First picture is radio power/light. Second picture I believe is the clock. Third picture are air conditioning connectors, which I believe were part of every harness regardless of whether you had A/C or not. The fourth picture is why I have my business.

Hope this helps.

Wiring is difficult if you don't have the experience.

I was thinking that Midlife was the first to answer

So my question:

Could I use the radio/power light connector to supply my 3 gauges? Cause I check the power on this one and I found something like 11.80 volts.

Was not a clock on my car, but the harness was probably the same in every cars, like with ac or non ac, as you mentioned.

On the second picture, they cut the wires (12 V permanent) to connect the radio, so yes it could be for the clock, and was probably unused on my car.

It's a little bit more clear, thanks.

You can't use the radio/light plug to power the 3 gauges, as two of the gauges need voltage reduced by the constant voltage regulator on the back of the dash cluster. 11.80 volts is not unusual at idle or with the engine off.

Save yourself trouble and send the harness out to mid life. Takes care off all the confusion in it. I will be doing that shortly for my project!

Mine looks even worse. I'm considering just going to a '67/'68 harness. It may be more work at first but how different can it really be. Besides, I'm going with aftermarket gauges and stereo anyways. And if I ever have any issues again, everyone makes a kit for a '67/'68.

They're pretty radically different. You'd do better to use the generic muscle car harness from painless. Maybe the 70 harness would be "closer" but you're still going to have to splice and route like mad. Cheaper and faster to send your harness to Midlife for a refresh
