ecu pinouts

[tegrakid06]

does any one know the pinouts on a p61 ecu i really need them

[cranny]

i made this myself , now theres 2 different OBD1 GSR ecu's (P61- 92-93 , P72- 94-95), i know not the differences between the 2 if any. i made these based on the manuals i have at my disposal so. here ya go and any questions ask away:

A04 - green/yellow - VTEC solenoid valve(GSR)

A05 - blue - #3 injector

A06 - orange/black - H02S(heated oxygen sensor)

A07 - green/blue - PGMFI main relay

A08 - empty

A09 - black/blue - IACV(idle air control valve)

A10 - empty

A11 - empty

A12 - green - to rad and condensor fan relays

A24 - black - ground for ecu as well as VSS , and VTEC pressure switch)

A25 - yellow/black - PGMFI main relay(power , also tied in with B1)

A26 - brown/black - ground for ecu as well as data link connector

 

B01 - yellow/black - PGMFI main relay(power , also tied in with A25 and connected to purge control solenoid)

B02 - browm/black - ground

B08 - green - PSP(power steering pressure switch)

B09 - blue/white - 7.5a starter signal fuse in under hood fusebox and comes out as black/red wire , and runs to starter cut relay and also runs to PGMFI main relay

B10 - orange - VSS(vehicle speed sensor)

B11 - orange - CYP(cylinder position sensor)

B12 - white - CYP sensor

B13 - orange/blue - TDC(top dead center sensor)

B14 - white/blue - TDC

D17 - white/yellow - MAP sensor

D18 - empty

D19 - yellow/white(than yellow/red from tower plug for LS , yellow/white all the way for GSR) - MAP sensor

D20 - yellow/blue - TPS(throttle position sensor)

D21 - green/white - MAP sensor

D22 - green/blue - H02S(heated oxygen sensor)

----------------------------------------------------------------------------------

all yellow/black's are tied together , they are power wires , and one goes to each of the following sensors

 

ELD (electronic load detector)

IAB (GSR secondarys)

EVAP purge control solenoid

IACV (idle air control valve)

VSS (vehicle speed sensor)

all 4 injectors to the second wire

 

yellow/white wire from 15A ECU fuse under hood , to PGMFI main relay

yellow/green wire from PGMFI main relay to fuel pump , black/white wire from fuel pump to ground

 

also a white/red wire leaning the data link connector , runs through interior lights 7.5a fuse under dash and from there to the 50A option fuse under the hood

for A/T , black/white wire from start position key tumbler to A/T position switch(wont start unless its in park or neutral)

white/green wire , second wire from brake switch goes to 20A horn/stop fuse
