I bought a front clip, jdm 90 integra with a B16A, and I dropped it in to the usdm 90 integra. The swap went smooth, vtec wiring & 2nd O2 sensor. The only thing that was left was the knock sensor, but my friend told me that ls motor had a knock sens., and everything was fine for 2 days, until check eng. light came on :2 long, 3 short- "knock sensor", so I run a wire streaght from ecu pin #B19 to the sensor on the back of the block, right next to the alternator.


Does anyone know the location of the pin on the ECU for the knock sensor on the non OBD ecu?

Thanx!!!

 

If you B16s ECU is a pr3 the knock sensor wire goes to pin B19. The 90 integra does not have a knock sensor. You will need to add this wire like the 2nd o2 sensor wire. HTH
