wiring-please someone HELP
2. I put a Grant steering wheel on the same truck, and I can't get the horn to blow, but it does work (tested to the battery). Is the Grant working off a ground and the horn itself working on a different ground and they are interferring with each other?
That's where I'd be looking.

As far as the horn goes. On your steering column connector there is a Blue/Yellow Stripe wire. A ground applied to this wire through the horn switch will activate the horn relay. The horn relay when activated applies 12VDC from the battery to the horn.
All info is straight out off the wiring diagram for your truck. All wire colors are original and could be different if a heavily modified wiring harness is installed.
Hope this helps.
