I have a 1989 Wrangler with a 4 cylinder, standard transmission. I have a switch that has broken that is on the side of the transmission, I thought it was the backup light switch but when I go to the parts store they show and list a switch with a wire attached to it just like the one I already have mounted in the transmission that is good. The switch I need has to threaded studes attached to it that the vehicle wiring harness just clips onto. Can anyone help? And where I maybe able to buy one.
