On a 30 year old car You desperately need to not use those heated seats... I did and look what happened:
Okay, all funnin' over. It is sad when someone talks something up so much like that ebay guy did, and it's freekin' obvious he has never ever, ever, never, seen what that "heated" wire seat does.
Watch for this post on a 914 forum:
"Whenever I plug in my heated seats, the car makes a buzz noise when I turn on the ignition. Is there another way to make the buzzing noise goaway instead of putting on the seatbelt? As well the seat does not get hot. The wire I hook it to does not have 12v. When I bypass 12v to it, it still has no heat. What did I do Wrong?"
Too Funny,
