and here are the ecu pinouts that go with that diagram
Ok now for the question. If you look in the link to the z1 wiring diagram, you'll see one thing labeled "EGR Control Solenoid Valve" with Black/Yellow and Orange/Blue.
There is also another "purge cutoff solenoid valve" with the colors Yellow/Black and red.
The egr box on the firewall is yellow/black and red, which matches the purge wires, but I thought it would go with the EGR control solenoid.
I'm a bit confused here lol.
1992 Civic CX with D15z1 swap.. work in progress
okay, I just remembered something. The o2 sensor on the d15z1 actually has 7 wires going do it. one is a 12v power and one is a ground I think. If it stops snowing by tomorrow I'll get out there and see if I can figure out where everything goes for ya.
