Primary connections include power, ground, tach signal, VSS signal, brake light switch, and the control switch itself. For power, the switched brown wire from the module includes a blade-type fuse tap, which worked perfectly with the car’s modern fuse box. Ultimately, you can cut off the fuse tap and connect the wire to any 12-volt switched circuit or directly to the ignition switch.
