Grant GT Horn Hookup

[bouncytruck]

Looks like your rig has seen some rewiring in the past (Is that speaker wire on the right?).

Follow the wires using the diagram. There is also a horn relay the wiring goes through before reaching the horn.

I'd say the first step is to see if the wires and the horn exsist. Pull your steering wheel and see if there are wires to the horn button. If so, trace them to see if/where they terminate. Use a mulitmeter to see if you have a solid wire from the horn button to the fuse box, fuse box to the relay, relay to the horn.

You can buy better versions of the wire diagrams though companies like LMC and Classic Parts of America. Someone was selling color versions on the board too so you might check with your favorite board vendors.
