ecu pinouts
k ill help u out
this its for a 88-91 CRX/Civic Si, HF and EX (this is accurate as i can get)
A1- INjector #1
A3-INjector #2
A5-injector #3
A7-injcetor #4
A8-lock up solenoid (auto only)
A13-ign power #1 for ECU
A15-IGN power #2 for ECU
A2-Power gnd #1 for ECU
A4-power gnd #2 for ECU
A16-Logic GND #1 for ecu
A18-Logic gnd #2 for ecu
A6- EVAP purge control valve
A12-fuel pump relay
A14- fuel pump relay
B6- check engine light
B15- Ignition control module
B17- Ignition control module
A11- IACV (EACV)
C16- Primary O2 sensor
B4- Radiator fan control
B10- CKP P (crank angle sensor pos)
B12- CKP G (crank angle sensor gnd)
C3-TDC P (top dead center pos)
C4- TDC G (top dead center gnd)
C1-CYP P (cyl sensor pos)
C2-CYP G (cyl sensor gnd)
B3- A/C Clutch relay
B13- starter switch signal
B20- Service check signal
B1- Back up voltage
C10- brake switch
B11- reverse light (HF only)
B14- alternator
B5- alternator control
C6-ECT
B19- ELD
C5-Intake air temperature
C9- PA
C7- Trotle position sensor
B16- VSS (vehicle speed sensor)
C13- sensor voltage
C12- Sensor gnd
C11- MAP
C15- map sensor voltage
C14- Map sensor gnd
if u wanna wire it up the Si way for MPFI i tell u to go to hybrid-k archives and get the DX to SI wiring... if their site its down PM em and i can give u the instructions.... the STD- SI differences are that the injectors cables norrow down to 2 cables in the engine bay, the distibuitor pinouts are different, and
