Well if a WC regardless of color fits the harness it is zenki, the kouki ecu/harness has a different pinout. The only difference between the black and red wc is that one is a couple years newer, they are interchangeable. Sounds more like a wiring problem than an ECU issue. Try to find another S14 SR to try your ECU on before getting another one.
