I'm running an Autometer electric speedo.
The cruise switch is from Rostra and wired through relays with results at the tach module harness connection as follows:
pin 14 brown =12v power with key on.
pin 4 dark blue=power when set button pushed
pin 5 gray=power when resume button slid over
pin 6 lite blue=power when brakes are applied
Standard tail lights, no led's
Help!!!
Might need to hear the 'long' story. A CTS-V doesn't use the brake pedal switch on pin 6, they use pin C1 62 that goes to an extended travel brake switch. Are you sure you have a truck tune, TAC, pedal etc?
