Need to extend the CAN bus harness on your Terminator, HP, or Dominator EFI System?  This harness will do that for you.  Matching ends mate with the CAN bus on these EFI systems.  Note:  Will not work on the Sniper EFI System CAN bus, as that requires gender-opposite ends.  To extend your Sniper EFI System CAN Bus harness by 4 feet, use Sniper EFI System Can Bus Extension, 4-Feet.
