The computer wiring is really a simple matter. If a hole does not already exist on the lower firewall, one will have to be drilled for the electronic controller. One wire goes to the 12-volt source, the other is the ground, another goes to the dash switch, and another to the foot switch. The last two wires go to the solenoid on the Gear Vendors unit and the VSS. A total of six wires, and it's no problem.
