Wire guage for 1981 GL 1100's horns?

Post by GL1100Newbie » Fri Mar 23, 2012 9:19 pm

Recently purchased (last week) a GL1100 (1981) that started life as an "I". When I picked it up it had lost all its farings and now I'm trying to make it a running naked wing. While I have mounted the horns as close to the existing wiring harness as I could, the existing wiring harness for one of the horns needs to be extended.

I though of making an extension for the horn that the existing harness does not reach. Can anyone tell me what guage wire I should use. Or I am open to any other suggestions, except returning to an "I" again.

The same as used on the bike.I think it's #18.
Personally,I bought 2 horns at a junk yard off a 78 f150 truck.
I used the original wiring to click a relay,pulled fused 15 amp battery to it and then to the horns.
The battery feed and horn wire were a # 14.
Really made the inspector jump.Never expected the bike to sound like a truck.

The factory wiring and horn switch are BARELY adequate to run the factory horns. If you're thinking of running aftermarket horns (like I did), or simply want your horn button to last, it's a good idea to have the original horn circuit just power the coil of a relay, and have the relay switch a new, fused line from the battery that supplies the horns. I did the same thing on my 1500.
