Helpful tip:
If your cruise control will not engage or causes the vehicle to go into 'limp mode' there may be an
1.
impedance issue between your pedals ground and the CRC controllers' ground location. To resolve
this, ground the CRC unit to the pedals ground location. Connect the black wire from the CRC unit to
the purple wire (PIN A) on the throttle pedal harness.
