When you shift the shifter into reverse, the reverse light switch, which is mounted to the tranny is activated causing the reverse lights to work. When you take it out of reverse the switch should turn off. Evans Wiring Harness told me that the pigtail attached to the harness, that is wired to the backup light indicator, should only get power when you put the car into reverse and go off when you take it out of reverse. But for some reason the indicator light is always on, which is probably due to a faulty wire harness or something in the socket on the bulkhead. Spoke to a friend of mine today who said that the pigtail light may be wired wrong or that there might be something wrong in the wiring socket on the bulkhead. He volunteer to take a look at it next week and hopefully we can find the problem. I will ask him about the micro switch at the shifter. Thanks for your help.
