I recently spoke with Evans Wiring Harnesses. They told me that the manufacture only installed the dash indicator light on 4 speeds. My car originally came with a 3 speed on the floor and it doesn't have a dash light. Just today I just installed one in the location stated by Avalanche. I connected the backup light switch wire harness to that empty connector as shown on the pic from Valkman above. The wire harness has a small pigtail that is suppose to be for the dash reverse indicator light. But when I connected to indicator light to it, the light comes on and stays on when I turn on the headlights, whether or not the car is in reverse. Any suggestions on how to correct this problem would be greatly appreciated. Thanks, Sergio
