85 Trans Am TPI. I have a relay in the passenger fenderwell in front of the door that is clicking on and off with key off, killed the battery. Found a grey ,green and white wires running to it that almost look like speaker wires running kinda loose under the dash. Does not look aftermarket , in fact you can hardly get to it and its toasty warm. Anyone know what this is and why its clicking on and off ? BTW, I'm resurrecting this car after 26 years in a shop/barn so there have been a couple surprises come my way, Thanks

 

Sounds like the power antenna relay.

Probably unhappy because the PA motor doesn't work right.
