Rally wiring harness
 

Looking for a 1970 firebird harness with rally guages in good condition.

Under dash or engine? AC ?
Having actually made these harnesses in various forms, I can tell you that you should get a new one ordered while you can as who knows what the wait times will be. If they run out of the correct connectors, even more wait.
If you know the wiring well, and have parts harnesses and connectors, your idiot light harness can be modified and wires spliced in.
99% of used stuff is hacked, rusted, or wrong.
