I'll be installing an aftermarket horn as well as a new steering wheel and was wondering where the closest negative ground point would be to the steering wheel position?

Also, on what point of the firewall could I run wiring through in order to meet the horn? While I'd imagine that it shouldn't be too serious, my other concern is that when turning the wheel, the wiring may get turned about, so I'd like to make the route as direct as possible.

 

Kayin, I haven't installed an aftermarket horn, but I'd imagine you could reuse the stock wiring, so no running of wires is necessary. At least I'd hope that's the case...it would make things 1001 times simpler.

Before installing the new steering wheel, make sure that you leave a lot of slack in the wires connecting to the new steering wheel's horn button contacts. Tape 'em on so they won't get pulled off. To check the slack, leave the center of the steering wheel off, but lightly attach the wheel to the column. Turn the wheel all the way to one side, then all the way to the other. There should be enough slack so the wires don't get tight at all when turning. And place them in such a way that they won't get tangled and lessen how much slack you have.

Lastly, the best ground for the horn I've found is right behind the main nut for the steering wheel onto the steering column. Works perfectly, and requires ZERO additional work

I dont know about you guys but on my car the steering column isnt grounded. The ground comes through on the clockspring so save yourself a lot of trouble and use the clockspring with the new wheel and the ground and horn wires that are already there.

 

Thanks. After reading the FSM, I found that the stock unit uses the clockspring, so I'll try and use that for the horn installation.

The wheel itself is actually quite easy to install, all that is required is the hub and perhaps a spacer (half inch to an inch should cover it) so that the turn signal and wiper rods don't get in the way of your hand when turning.

 

youre right about the spacer, and youll need to cut a hole in the hub for the clockspring connector.
