I am going to convert my 5 wire o2 on my d15z1 to a 4 wire with a p28 ecu.

I need some help on what else needs to be change. Do i need to get a 4 wire o2 connector or are they the same??

How about the 5th wire...What do I exactly do there??

I was told some pins have to be moved around. Does anyone know which ones it is, etc or have a pic of the pin out and where to move them to?


Thanks a bunch. I tried searching but didnt find anything that really helped me out.

WIRING A 1995 OBD1 B18C1 INTO A 1994 VX CIVIC USING A USDM P72 ECU

LOCATE THE 6 PIN PLUG BELOW ON THE PASS. SIDE VX SHOCK TOWER



The wires are in the following order:

ORG/BLU BLU/GRN WHT/BLK

BLU/YEL WHT/BLU YEL/WHT

REMOVE THE FOLLOWING WIRES FROM THE 6 PIN VX PLUG

ORG/BLU - O2 SENSOR

BLU/YEL - KNOCK SENSOR

LOCATE THE 10 PIN PLUG PICTURED BELOW THAT IS ON THE VX SHOCK TOWER



The wires are in the following order:

BRN/BLK EMPTY BLK/RED

ORG WHT ORG/BLU WHT/BLU

BLU/GRN BLU/YEL EMPTY

REMOVE THE RUBBER PLUG FROM THE TWO UNUSED SOCKETS

INSERT THE ORG/BLU (O2 SENSOR) WIRE INTO THE SOCKET BETWEEN THE BRN/BLK WIRE AND THE BLK/RED WIRE. (TOP CENTER SOCKET IN PIC)


INSERT THE BLU/YEL (KNOCK SENSOR) WIRE INTO THE SOCKET NEXT TO THE OTHER BLU/YEL WIRE. (BOTTOM RIGHT SOCKET IN PIC)

NOTE - IF YOU ARE USING A CHIPPED P28 ECU YOU WILL NOT NEED TO WORRY ABOUT WIRING UP THE KNOCK SENSOR


YOUR NEXT STEP IS TO MOVE THE RED WIRE ON YOUR ECU HARNESS FROM A20 TO A17 FOR YOUR SECONDARY RUNNERS FOR YOUR INTAKE MANIFOLD. THEY SHOULD OPERATE AS SEEN HERE .

ALL YOU HAVE LEFT YOU DO IS PLUG IN YOUR ECU AND PLUG THE 3 VX SHOCK TOWER HARNESSES INTO THE GSR MOTOR HARNESSES.

If you have any questions PM me.

Im not swapping a GSR motor in or a GSR harness in. Im just want to make it so I can use like a d16z6 o2 sensor(4 wire) on my VX motor cuz a VX o2 sensor is to much to replace.

So will this still work??

 

Its the same directions

 

Alright well Ill give it a wirel(sp)

 

i recently built an lsvtec b16/b18 p28chippd ecu with obd1 ls engine harness. Im getting cel code 41(o2 sensor), i replaced the 4 wires o2 sensor with oem and ran four new wires straight to the ecu. i tried doing the instruction above(WIRING A 1995 OBD1 B18C1 INTO A 1994 VX CIVIC USING A USDM P72 ECU) but i noticed that i dont have the same shock tower clips on the passenger side. i was just wondering if anyone dealt with this problem before, i would really appericiate if someone can help me out.
