Probably still on top of the column under the dash with the wires. Believe Gregg has moved his to a 4-speed if I remember right. He should be back.

Yes John, I converted to a floor shift column when restoring back to a Muncie 4-speed, so my backup lite switch is mounted on my transmission shifter.

Mr. Muha might be correct...look down at the base of your steering column. If the car was originally a column shift, there may still be a switch that gets manipulated by the rotation of the outer sleeve of the column. An inner sleeve moves a pawl mounted on the bottom of the switch, and controls neutral safety & B/U lights.

Look for a pair of wires, most likely with a plastic terminal spliced onto it, attached to this switch. If your car has been hacked up over the years, converted to manual transmission on the floor, you may just want to make up a switch of your own by installing a plunger-style switch on a thin steel bracket, then mount to the back of your shifter. Reverse shifter arm will swing back and depress the switch activating your lights.

Good Luck & let us know how it works out.

The connector should have 2 wires: pink-power, green-wire to rear lights.

SUCCESS, you guys are the best, I found the 2 wires with the connector spliced to them, under the dash at the base of the column. I did mount a switch with an arm on a bracket to the floor so when I engage reverse, BACKUP LIGHTS!!! Yeeee Ha. You guys are great thank you aging for the information it is greatly appreciated. This is a project that is getting off the ground and every little tip is hepful. I will most certainly be talking with every one again. Thanks Scott
