what do i do with pin b1, b1 goes to a25 and a25 goes to obd0 a13 and o2 black under green. anyone have pics of what it looks like?

 

OBD0 pins on left - OBD1 pins on right

A Plug:
A1 (yel) -> A2 (yel) Injector 4
A2 (blk) -> A23 (blk) Power Ground 1
A3 (yel) -> (unused) *
A4 (blk) -> A24 (blk) Power Ground 2
A5 (red) -> A3 (red) Injector 2
A6 (grn) -> A20 (red) Evaporative Purge Valve
A7 (red) -> (unused) *
A11 (blu/yel) -> A9 (grn/wht) IACV
A12 (grn/blk) -> A7 (grn/yel) Fuel Pump Control 1
A13 (yel/blk) -> A25 (yel/blk) ECU Power 1
A14 (grn/blk) -> A8 (grn/yel) Fuel Pump Control 2
A15 (yel/blk) -> B1 (yel/blk) ECU Power 2
A16 (brn/blk) -> B2 (brn/blk) Logic Ground 2
A17 (blk/yel) -> (unused)
A18 (blk/red) -> A26 (blk/red) Logic Ground 1

* Unused injector wires. If you are making an adaptor harness, there is nothing to be concerned with. If you are cutting the old plugs and using new ones, you can tape them and set them to the side. Or you can make the connection above the split for a cleaner install.

B Plug:
B1 (wht/grn) -> D1 (wht/blu) ECU Memory
B2 (orn) -> A6 (orn/blk) Oxygen Sensor Heater Control **
B3 (yel) -> A15 (blk/red) A/C Clutch Relay
B4 (yel/grn) -> A12 (yel/grn) Cooling Fans
B5 (wht/yel) -> A16 (wht/yel) Alternator
B6 (grn/orn) -> A13 (grn/orn) MIL (Check Engine Light)
B8 (blu/red) -> B5 (blu/red) A/C switch
B13 (blu/wht) -> B9 (blu/wht) Starter Signal
B14 (blu) -> D9 (pink) Alternator
B15 (wht) -> A21 (red/grn) Ignitor 1
B16 (yel/red) - B10 (yel/blu) VSS (Speed Sensor)
B17 (wht) -> A22 (red/grn) Ignitor 2
B19 (grn/red) -> D10 (grn/red) ELD (Electric Load Detector)
B20 (brn) -> D4 (brn) Service Check Connector ***

C Plug:
C1 (orn) -> B11 (orn) CYP P
C2 (wht) -> B12 (wht) CYP M
C3 (orn/blu) -> B13 (orn/blu) TDC P
C4 (wht/blu) -> B14 (wht/blu) TDC M
C5 (red/yel) -> D15 (red/yel) IAT (Intake Air Temperature) Sensor
C6 (red/wht) -> D13 (red/wht) CTS (Coolant Temperature Sensor)
C7 (red/blu) -> D11 (pink/blk) TPS Output
C9 (red/wht) -> (unused)
C10 (grn/wht) -> D2 (grn/wht) Brake Signal
C11 (wht) -> D17 (wht) -> MAP Output
C12 (grn/wht) -> D22 (grn/wht) Sensor Ground
C13 (yel/wht) -> D20 (yel/wht) Sensor Power
C14 (grn/wht) -> D21 (grn/wht) MAP Ground
C15 (yel/red) -> D19 (yel/grn) MAP Power
C16 (wht) -> D14 (wht) Oxygen Sensor Output

Added Wires (Pins are, of course, on 1992-1995 plugs):
A4 (orn/wht) -> VTEC Solenoid
D3 (white) -> knock sensor ****
D6 (orn/blu) -> VTEC Pressure Switch
B15 (blu/grn) -> CKP P ****
B16 (blu/yel) -> CKP M ****

 

thanks mr zcspeed lol

 

is this one wrong?

they are essentially the same - the only difference is that the one i posted is for converting a stock DX harness (one that hasn't been converted to MPFI) to OBD1 and MPFI at the same time - the one you posted is for converting a stock OBD0 MPFI (or already MPFI converted DX) harness to OBD1 - the one i posted has the OBD0 pins on the left and the one you posted has the OBD1 pins on the left

 

oh okay, i dont have anything that is dual point, i already had the multi point swap its a cake swap, do i have to run a crank sensor, that is next to the crank pulley?

 

what about OBD1 pin D4 one says to toggle switch to ground and the other says ->OBD0 pin B20?
