Wire colors at horn connector

OK.
With this connector off the horn but battery, fuse and wire good:
G-W shud hav steady 12V
G-R shud hav 0V
Put pos probe on G-W and neg probe on G-R. Shud read OV or close. Push horn button, u get 12V.
RESISTANCE CHECK:
One probe on G-R, other on gnd. Shud be open. Push horn button and u shud get as close to zero ohm as possible. Higher resistance means problem with connections or horn button.
HEY! Nice FJ60 passed as I was typing.

Standing on a corner in Ocean Beach, Californa, it's a red FJ60!...

Suweet 60.

Yes, manufacturers often fix what are not broken, including wire color coding that it makes things harder to troubleshoot.

AHA! You missed what I had highlighted.
Happens when you're too eager to jump into the water before checking.

Horn Relay Retrofit

I added relay to my horn circuit so it doesn't sound like that little guy with big ears from Anaheim, CA with his balls caught in a trap - LOL!
No need to tear into steering column contact because not that contact carries low current.
