Don't know if this is of any help? http://a12mopar.com/yabb/YaBB.pl?num=1307756102;start=all
Ok so in the engine bay the wire for the backup lamp plugged into terminal Z. Inside the car at the bulk head terminal Z was empty. I took the black wire with white tracer and connected it to terminal Z. I didn't see a ground wire off the light. Hopefully I did this correctly
4 speed?
Should connect to a switch on the shift linkage.
I stand corrected. I guess I used the term "linkage" a little loosely. I guess I meant that it was activated by the linkage.
