GM Throttle Wire Colors
GM colors and certain pins can be different, let alone aftermarket harness colors.
The GM throttle pins are labeled A through F.
B and E must retain the same voltage ranges in order for the pedal and cruise to function.
A, C, D, and F can be ground or power, as our throttle harness merely acts as a pass through.
When looking for a ground reference to ground the CRC-2000 to, one needs to verify the correct wire.
