Where do the wires go? Wiring a 904 transmission

If your car is column shift the reverse lamp switch is on the top side of the column down neer the brake pedal. If your car is console shift the same factory connector will be found in the same location but have another wire harness plugged into it extending those wires to the floor shifter. Regardless, extend and route those 2 wires through a rubber plug in the firewall and tape in with the neutral safety signal wire to the trans. Now that switch will operate the reverse lamps.
