1983 310 Classic Backup Lights

[cole3444]

Trying to find out if the 310 backup lights work off the neutral/reverse switch that is mounted on the steering column. Wires are connected to the neutral switch but I don't have any wires running to the prongs for the backup. Since it has the Cummins/Allison transmission it doesn't have a reverse module where it calls for on the tranny so I assume that the original wiring is still in use. Have no clue what wire colors run to the switch. I have many unplugged wires under my darling dash. Found all the wires when I got the speedo and tach moved down to the dash cluster from the top of the dash where the old ones were that was installed when the Cummins was put in, all electrical hookup on both no trans cable to odometer. Any help will be appreciated.

Hey,
I don't know if this is any help to you, concerning your backup lights. But, on my 325 , on the drivers side (left) my marker light that is half way down the side, for some reason, comes on when I put it in reverse. Weird I have LED tail lights, and my backup lights are in my bumper. Still haven't gotten them to work, I'm thinking maybe that side marker light was wired that way to let the driver know he's in reverse. I haven't looked into it future, but that wire may be the lead from the steering wiring.
Does anybody else have this thing on the side marker light? DJ

I have the Allison T1000 and the natural/backup switch is on the transmission over the shiftier shaft. But then mine isn't exactly original equipment.
