Professional Series OBD-II Programming Switch Assembly (BLACK)

Power Supply Sold Separately

This professional series switch assembly is to be used in conjunction with any of our professional series ECU Extensions. Made of aircraft-grade 6061 aluminum, our professional-series benchtop switch assemblies are what you need to get the programming out of the car and onto your benchtop. Switch assembly receives regulated 12V DC power from an AC to 12V DC (5A) Power Supply (available below) for an easy and simple power source from any wall outlet. The ECU is protected by an internal, resettable, 5A fuse on the circuit board. The OBD-II connector passes through to the ECU connector to meet SAE J1962 requirements for compatibility with the OBD-II protocol. If we do not offer an ECU harness for your application, you can make your own by using connector 100-00611. An optional power cable with 18ga leads for external power supply or battery hookup is available as EFI P/N 100-00680.

Includes pass-through harness for GM ECUs (EFI# 100-01032).
