1985 K20. Need inspection to get tags. How to wire external horn button?

[Nasty-LSX]

My horn does not work. Im going to wire in a small horn button. What is the best easiest way to wire it up
without running a wire all the way to the horn?

Anyone know the horn wire color running into the column? How have you done it. Thanks

All you need to do is run a ground through the button to the horn relay under the dash. I think it is mounted on a courtesy plate or something like that. Two relays above the gas pedal. Just have to find the right wire.

Horn Button

Hi, I know this is a really dumb question but anyway I have an 87 r10 and I can't for the life of me figure out where the horn button inside the cab is.... No wires runnin in the steering wheel or on the floor beneath the parking brake?? Can someone tell me where else to look plz? Thank you...

Convenience center relay. That’s it

Convenience center mounting

I have an ‘85 c10 standard shift that I’m restoring. A body guy completely gutted the cab and I’m reassembling it. I can’t for the life of me figure out where to mount the “convenience center”. It has the hazard flasher, a relay and something else. It has a bracket and two mounting holes...

The ground trigger in the column is a black wire.

Start at the relay in the convenience center. Unplug it, test for power on the orange wire. If you have power, use a fused jumper wire to jump power from the orange wire to the dark green, the horn should sound. Next, test for continuity from the black wire of the horn relay to ground while pressing the horn button. No continuity, means either a wiring issue in the column or someone has taken the column apart and omitted a few parts.

Probably not your issue, but when I bought my truck, the horn didn't work.
Pulled the horn cover off the steering wheel just to look around.
Pulled the horn button out, stretched the spring a little and put it back in and it worked.
Never got around to getting a new spring, but it's still working after 7 years.

Ok thanks for all the info. I will mess with it tonite.
I forgot to say when I hit the horn button my horn
relay buzzes. Could I have a bad relay? If I test it like Matt69
says and it works, then I should Have a bad relay?

here is a visual of the convenience center. As stated above. ground black wire to complete circuit to relay. Relay gives power to dark green to horn.

yes, could be bad relay.

the terminals on the horn itself were funky on my 85 k20 super double xtra heavy duty.
scuffed them up shiny and horn honks fine right.

good luck

we call that a FUSE PANEL in AMERICA. speak english or LEAVE.

This is were I feel stupid. I was going to try everything else before checking to
see if there was a fuse in the panel.

YEA, THE FUSE WAS MISSING. I feel so retarded It works fine now!

 

[Jgonick]

Somewhere around 85 I think, they added separate fuse panel called the convenience center.

Thanks Jgonnick!!
