Two questions
#1 Pin 15 from circular connector is ground-but has trace peeled up-anyione know where it goes?
#2
At the back of the instrument cluster above the dimmer rotary control and below the oil pressure input is a Black relay box
What is it ?
I have not seen this "relay" on any other instrument clusters-anyone know what it does?

1. Pin 15 goes all over the instrument cluster. Its the ground for the lights bulbs and clock.
2. If the black box you are asking about is behind the speedometer, thats the engine speed sensor. It has something to do with emission control on my car.
