I used the same CPS. The plug on the B/A (2-pronger) is the Reverse lights...the plug on the passenger side of the AX-15 is the reverse lights as well. You have 2 options, splice them together or go a plug from the boneyard. My truck is an 89 and my donor was a 90 XJ, so I just swapped the plug where it connects to the wiring harness from the tranny...plugged right in!!
Clear as mud?? Good Luck
