To maximize weight savings, many S2000 owners remove the Air Pump located in the front driver side bumper. This will immediately make the ECU throw a check engine light (CEL).
Ballade Sports Air Pump Bypass, once wired into the ECU harness, will emulate as if the original Air Pump is still installed. Fakes the signal if you will. This gets rid of the annoying check engine light.
This unit comes with complete wiring instructions and diagrams.
Note: The PCB board comes pre-shrink wrapped (as shown) for protection.
