backup light wiring connection

[GRAY WILSON]

I have a 68 GTX 4 speed, and the backup light switch was not hooked up. I removed the trans to install release bearing and had to install new switch and wiring harness. I can not find where to plug the harness to. Can someone tell me where to look, or where it would come from.

runs to the wiper bulkhead plug section, cavities C and D. ( the ones at a side of RED and BROWN wiper wires on plug )

Does it go down the fire wall ,under the car to the trans?

yeap

this is a wiring trace diagram for laters since includes auto harness which by 68 was really just the NSS ground without the back up lamp switch built in ( these got the switch on shifter ). I guess earliers are kinda similar.

there are some wiring looms available to run this wiring

this uses to be the plug for the back up lamp as a pigtail on the wiper bulkhead plug. This is specifically 69 auto... I guess 68 4 speed is like this ????
