Important Wiring Notice

This is a passive wiring cable and does not itself provide diagnostic, coding or ECU programming functions.

Do not determine pin functions from wire colors alone. Wire colors are not a universal OBD-II pinout standard. Always verify continuity, pin assignment, voltage and polarity before connecting the cable to a vehicle, ECU, diagnostic interface or programming device.

Incorrect wiring can damage electronic control modules, diagnostic equipment or vehicle electrical systems.
