no fire,a bit lost....

If you don't have either the harness for the car or the one from the transmission, get the correct one for the car and with any luck it will plug onto the switch. The switches were redesigned and some plugs fit good and others don't. If you have the plug and a little wiring still on the transmission, you can wire it into the existing car harness with a few simple wire connectors. You'll need an accurate wiring diagram, wire terminals, electrical tape, and a good crimper tool.
