I have been informed that Ford changed the horn harness on the 73 to 79 F- series. I bought one on line. The relay is not the same. It has 2 rubber body plugs / grommets. Oh?
Loose red wires with wire nuts do not look correct. Please advise.

 

Help us help you! one of your previous seven threads, someone asked for pictures to help us understand what you have (why you have three horns, your new harness, etc), someone mentioned they live in WI and offered for you to come took.....

One would assume that a horn circuit would be an easy fix. I guy out east sold me a complete horn harness. The relay is no match. It has 2 rubber body plugs / grommets into the cab. However, I can't find
the old harness holes. Therefore, perhaps someone with a 75 F-150 that lives near Milwaukee might let me study his truck. So much for an easy fix.

 

You need to post pictures of both the harness and the firewall before anyone can help you further.
