    So I have my swap in, everything works, but I'm trying to get the car bar'd legal (90 EX sedan with b18a1) Everything was basically drop in. But I'm having trouble trying to figure out how to wire the firewall sensors. The Integra firewall sensors have 4 wires and 2 sensors, while the Civic firewall sensor is one sensor and 2 wires.

    From what I gather is that the PR4 doesn't even have the same pinout for the Purge Cut Solenoid Valve which on the Civic is A06, and the Regulator Control Solenoid Valve wire from what I gather is pin A10 on the PR4 pinout, and A10 is not used on the Civic stock wiring.

    So my question is, can anyone confirm which pin on the ECU goes to the PCSV? Is it the same A06? Or is my info wrong on pin A06 being a ground on the PR4 ECU?

    Also, does anyone happen to have one of these pics for a 90-93 Integra?
