ok so heres the deal... im swapping a obd1 d15b into a 1991 civic si(mpfi already). the motor is in, and most of the sensors are pluged up. obd0>obd1 conversion harness is pluged up with a p28 ecu, my main problem is how to wire up the sub harness i have 9 wires left but dont know where they go, and i cant seem to find any good resources online about this.

maybe someone can lead me to a good source, or lemme know where they go?!?!?

any help is appreciated!

 

if its a rywire harness. look at the instructions.

Only if its a rywire harness, if its not, look at there instructions.

 

I wish it would have came with some instructions.

 

what color are the 9 wires I can probably tell you where they go

 

most likely the wires are:
4 wires for a 4 wire O2 sensor
1 wire for Knock sensor
1 wire for VTEC Solenoid
1 wire for VTEC Pressure switch
1 wire for MIL (connect this wire to a ground with a switch between)
1 wire for IAB's (only for GSR manifolds)


you can find their location using this guide

here's what mine was
Blue-O2 sensor heater control(O2 BLK wire)
White-O2 sensor signal(O2 WHT wire)
Violet-VTEC solenoid signal
Gray-VTEC pressure switch signal
Green-Intake air bypass signal
Orange-Knock sensor signal
Red(2)-Power (IAB, O2 BLK wire)
Black(3)-Ground (SCS, VTM. O2 GRN wire)
Yellow-Service check signal
