Can you be any more specific as to what you need? For the wiring, just find a pinout diagram and trace the wires. PITA, but you'll know it's right.

Just plug the OBD2 B18C harness into your Civic's shock tower plugs. Done.

Then just add the vtec, ks, & iab wires to your ecu plugs.

Find an OBD1 P72 to use with your B18C and call it a day.

 

can't i just plug the motor harness into the civic harness and run the obd1 to obd2a and call it a day?

yes, if you have an obd1 ecu that's exactly what you need to do. Like boomslang said, just run wires for vtec, ks, and iab. And to make it really easy...

Vtec solenoid - A4
Vtec pressure switch - D6
Vtec pressure switch ground - A26
Knock Sensor - D3
IAB - A17

Good luck man.

 

i guess ima obd1 it then. thanks for the help
