TECH: 5th Gen Accord OBDII ECM/PCM Terminal Arrangement

I know some people wanted this, so I'm posting it up.
This is straight out of the factory service manual.
***Some wires may be the same color on the same connector, so also go by pin position. Pin position goes from left to right, top to bottom; looking at the connector with the latch side up.***
***Column 1 is wire color--->column 2 is terminal name***

 Connector A (32P) 
YEL--->INJ4 (#4 FUEL INJECTOR)
BLU--->INJ3 (#3 FUEL INJECTOR)
RED--->INJ2 (#2 FUEL INJECTOR)
BRN--->INJ1 (#1 FUEL INJECTOR)
ORN/BLU--->SO2SHTC (secondary heated O2 sensor heater control)
ORN/BLK--->PO2SHTC (primary heated O2 sensor heater control)
RED--->ESOL (egr control solenoid valve)
GRN/YEL--->VTS (VTEC solenoid valve) *3
BRN/BLK--->LG1 (logic ground)
BLK--->PG1 (power ground)
YEL/BLK--->IGP1 (power source)

WHT/GRN--->ALTC (alternator control)
YEL/GRN--->ICM (ignition control module)
BRN/BLK--->LG2 (logic ground)
BLK--->PG2 (power ground)
YEL LT BLK--->IGP2 (power soure)
ORN/GRN--->IAR SOL (intake air resonator control solenoid valve)
GRN--->FANC (radiator fan control)
GRN LT WHT--->2WBS (evap bypass solenoid valve) *1
ORN/GRN--->VSV (evap control canister vent shut valve) *1

 Connecotr B (25P) FOR AUTOMATICS ONLY 
BLU/YEL--->SHA (shift control solenoid valve A)
GRN/BLK--->LC B (lock-up control solenoid valve B)
YEL--->LC A (lock-up control solenoid valve A)
GRN/BLU--->ATPD3 (a/t gear position switch)
GRN/WHT--->SHB (shift control solenoid valve B)
WHT/GRN--->ILU (interlock control unit)
BLU/RED--->D4 IND (d4 indicator light)
WHT/BLU--->NMSG (mainshaft speed sensor ground)
ORN/BLU--->NM (mainshaft speed sensor)

RED--->SCS (service check signal)
LT. GRN---K-LINE (sends and recieves scan tool signal)
WHT/YEL--->VBU (voltage back up)
WHT--->CKPM (crank position sensor m side)
RED--->TDCM (top dead center sensor m side)
BLK--->CYPM (cylinder position sensor m side)
GRN--->PSPSW (power steering pressure switch)
WHT/RED--->ALTF (alternator fr signal)
ORN--->VSS (vehicle speed sensor)
BRN--->PFSW (evap purge flow switch) *2

 Connector D (16P) 
RED/BLK--->TPS (throttle position sensor)

Great info! Does this apply to OBD I (94-95) Accords as well? Where did you find this info??

Ok I have the helms for my car (94) and I couldn't find this info anywhere in it. There is no index. What section/heading do you look in. BTW, I also have the helms electrical supplement and I haven't seen it in there either.

Quote:

in your service manual, its in the fuel systems section (the section with the fuel nozzle thingy). at the very beginning of that section, there is a table of contents for that section. Look for something like ECM Terminal Arrangement.

when you find it, please look over it and post any differences there may be if you dont mind.
