ok guys.....first one to answer gets a 6pack of beer..............i just swapped in an OBD1 b18b1 LS motor into my 92 civic VX..........everything wires up fine, EXCEPT for the o2 sensor......i am using the VX engine harness and the LS p75 ecu.....

i need to know how i wire up the 4wire LS oxygen sensor into my 5wire (wideband) vx engine harness....thanks in advance

 

Why didnt you use the wireharness that came with the engine? It would be plug and play.
