This is a standard horn relay used in many older GM cars and trucks.  Also used in AMC Jeep CJs 1976-1986.  Tested and works as the video shows.

I've included a picture that shows the terminal pinout in case you are wiring in this relay yourself.  Do NOT reverse the polarity as it will smoke the relay.

I ship all parts in one day, and often the same day if the order is received soon enough.  If you see a longer ship time listed, I am out on a Jeeping trip and will mail your item(s) as soon as I get home. 

I buy and sell on eBay to support my jeep habit! Check my feedback and bid with confidence. Please check out my other auctions!
