im installing a air horn setup i know that 87 on the relay go to the compresser and 30 goes to the fuse to battery but where is 85 and 86 go to im using my stock horn button

 

If you are using the lead to the horn ( pos trigger from the horn relay to the horns ) terminal 85 would be wired to the horns, and terminal 86 is ground.

The clock spring switches the ground on the factory horn relay.

Terminal 85 should be to the horn wires, the Yellow w/ Green stripe wire.

 

thanks thanks what i needed to know

 

What horns you got there??

 

picked up set off my buddy he got rid of his truck dont know what brand there are but they where dam loud on his truck.should get the white hairs moving out of my way down here in florida

 

Don't be suprised . Most won't know what to think and just stop in the middle of the road . Ive had that to happen . Well , I was coming up on some tracks .
