I'm replacing my oem gauge pack with the Genome gauges and thought the power cord could plug into where the oem gauges plugs in behind the radio onto the jumper harness but that didnt fit. Not sure if my gauges came from a JDM Sti or WRX so maybe they have slightly different harness. Anyway, anybody have any suggestions? Do I need to cut and splice the jumper harness wires or is there somewhere else to plug the wirs into?
