Re: 69 coupe sb powerglide trans shifter backup light switch
Well, the pink wire coming into the switch is the 12 V feed, so that is the first thing to check with key in run (or acc). If you have 12V, you can then connect a jumper wire between the pink and light green, then turn the key and see if the lights are on. If they come on, then the switch may be bad. If you have a multimeter, you can put it into "continuity" mode, hook to both switch terminals, and move the shifter back and forth and see if you get a tone.
