Wondering where the a/c time delay relay is mounted. I am placing a/c wiring back in car but cannot find a reference on where to look. I am guessing I don't have it but need to confirm.

Any help would be appreciated

Thanks again

There is a time delay relay but it's not for the A/C.  It's a small canister that looks like a turn signal flasher.  However, it's about half the diameter and about 1.5x as long.  It gets taped to the steering column down by the pedal area.

hmm. On my a/c under dash wiring there is on the harness end  2 wires that have 2 female connections separate from each other. Will get pic tonight.

Attached pic of what I thought maybe needed for car a/c

That doesn't belong on a 70 Cuda.....

So I think I figured out what the wires I thought where for a time delay rely are really used for on interior side. Not 100% but I think I am right.  I have a green and black wire with a female connector on each inside car that appeared to go nowhere. After almost completing the engine bay wiring I looked under the dash at the firewall bulkhead connector for the fan and a/c low pressure switch and noticed no connections in the bulkhead connector. The a/c wiring harness was separate from car when I received it so I assumed all connections were on the main wiring harness.

Hopefully I am right and can move on from this issue.

I have to admit that placing a/c back on car sucks. I have a negative on the a/c unit on engine I have to figure out where it bolts also, but small issue on that one.

There was a time delay for the headlights (which is what that small silver canister is for). It was an option, but the harness does exist for it and is located just inside the left kick panel.

The small silver canister is a delay relay but it's for a few small panel light, & the key light.... The head light delay relay is much bigger....

Correct.
