Need help. I Bought a non excisting horn relay on Ebay

OK sounds like you already did the right thing and so did the seller.....just remember EBAY is an AUCTION,,,,and as an AUCTION their job is to make you believe YOU NEED that part at that minute, to get you to bid bid bid!!!..... you keep your eyes open I am guessing there will be MORE NOS relays getting listed in the future...... try Roseville chrysler in roseville Michigan....they possibly have one ....but dont look for bargain basement costs LOLOL
dig around a lil you will come up with one
