I am trying to add air horns to my Enclave and wanted to get a connection/trigger at the horn relay. I do not have a schematic, but
in the underhood fuse box there is a relay marked "HORN" I tried with no results to get 12v off that relay but was unsuccessful.
This stumped me.... I think the relay marked "HORN" is part of the security system to turn on the horns. The reason I believe that...
I pull that HORN relay and the horns still work.......anyone have a schematic they can post.
PS I solved the problem by tapping into the horn harness but still wonder about that HORN relay
