Hey guys,

I recently swapped a OBD2A GSR engine (with the engine harness and ECU) into my 1997 Integra LS I did NOT have the firewall harness to the ECU. So, with that being said... I have some wiring to do. I have a CEL for VTEC, which is easy enough to wire but there's one for the crankshaft positioning sensor, TPS sensor and an emissions issue which I'm assuming is the IAB sensor (I am using a Skunk2 intake manifold/throttlebody). Does anyone have the pinout diagram for the GSR and LS firewall harness? That would make my job a lot easier. Also, any tips as to how I can bypass the IAB sensor? If there's already a thread for this, please link it in the comments.

Thank you,

IAB won't throw a code and is basically bypassed without hooking it up (stays open all the time). If your code is P1337 that's for crankshaft fluctuation sensor at the crank. You'll need to bypass or get a US oil pump with that sensor included. As far as TPS are you sure you didn't swap the TPS and MAP sensor connector around? They are close and use the same connector. Post the exact codes if you can

I got it all taken care of, just had to run some pins to the ECU due to my firewall harness being an LS while the engine harness was a GSR.
