Where might that pin be?
The two electrical pins I'm talking about are the ones that go into the reverse light switch, port side of the transaxle, up and aft of the left CV joint. One will have 12 power (with the key on) the other will go to the reverse lights. Gray with red wires?
If you remove (carefully) those pins and touch them together (with the key on) the reverse lights should illuminate. If they do, then the problem is with the switch. If they don't, then you either don't have 12V to one of those wires, or you have discontinuity from the other wire to the reverse lights. Or burned out lamps.
Could also be fuse 9, but I think dash warning lights are on that same circuit. - GA
