Mystery wire ?

**RPOLS3** · #1 03-07-2010, 03:00 AM

Anyone know what this orange wire might be for? I have owned car since 1987, found this tucked back into the harness last winter. I have made no modifications to harness since I owned it. All electrical things seem to be working fine.

Car is 72 Chevelle BB/TH400/AC if that helps.

Thanks

Isn't that for the firewall mounted fan "blower" motor that snakes under & around the AC suitcase?

orange is usually the blower motor but thats a little heavy for that

I think that's the wire for the A/C that has (supposed to have where it was clipped) the inline fuse?

I know this much, you have a nice clean engine bay there.

I think That the orange wire is not used when you have A/C.
I think it is just cut and taped to the wire loom from the factory.

If you are referring to the high speed blower motor inline fuse, that is in place and functioning so I think I'm OK there. Thanks

I have the same mystery orange wire on the 69 Nova 350 A/C

Thanks - just out of curiousity then - what was it used for if NO a/c? I would have thought that the a/c would require more wires, not less.

Assembly manual not much help, just shows orange wire to blower motor.
