Reverse lights not working

Hey there,
Have a 71 Dodge D100. When purchased it had the 3 on the tree removed and a 3 speed on the floor put in. I fixed the speedometer not working issue, but don't have reverse lights. Is there something "buried" in the steering column that needs to be jury rigged - or? Thanks in advance.

The reverse light switch is usually on the transmission, not the column.

Right. So I need to find those reverse wires and wire them to the reverse switch on the new trans?

Yes. And its possible that the previous owner removed those wires or just didn't plug them back in. I'm assuming only the shifter was changed & the truck still has same transmission, correct?

It's the 2 outer wires on the neutral safety switch. One has 12 volts+, the other goes to tye backup lights. The center wire is the neutral safety.

My guess would be starter relay, ground wire

I think a good question to ask is will it start in gear?
