Hey guys. I have an 86 xj6 that has had the horn circuit removed from under the hood by the previous owner. It has 2 new horns mounted under the front bumper and that's all. The are no relays or anything. What I need to know is where does the horn wire come through the firewall at? Passages side or drivers side? And what color is that wire.
Thanks in advanced.

Not sure about the firewall question, but it seems unlikely that they would have just pulled the horn cct out of the harness.

If it helps, the horn relay is normally front US passenger side , low down in engine bay. Colours you are looking for:

Green = relay power 12V ignition
Purple/Black trace = relay earth via horn button
Brown/Purple trace = 12V horn power
Purple/Yellow trace = horns

 

it is a separate harness from the relay to the horns. The Relay is almost hidden but if you find it, check to see if there are wires connected to it from the main harness.
