Kenji- I am doing a JDM ITR Header & Testpipe however I have a 96 GSR OBD2 ECU in my 2000 Si (with your wiring harness). I want to splice into the harness to add a circuit of some type that will trick the ECU to not throw a CEL because of my Test pipe. What wire do I splice and what type of circuitry do I need to do this?

Thanks!
