There are a million threads on how to switch from a 5-wire to 4-wire o2 sensor but not vice versa because everyone swaps different motors into a VX but not a VX motor into a different car... But I happened to have a 97 civic EX with with an OBD2->OBD1 harness and a 93 OBD2 VX motor/ecu... So the wiring harness has 4 wires and the o2 sensor has 5 and the ecu is looking for five... So, basically all I need to know is what are the 5 pins on the OBD1 VX ECU for the O2 sensor and the corresponding wire colors from the O2 sensor... I looked at some FAQ and I have found the pinouts for the 92-95 ecu but I can't identify all 5 pins.... If anyone can help that would be greatly appreciated...

 

Bump... no 5-Wire O2 Sensor gurus?

 

So nobody knows or knows where I can find the answer?.. I've tried searching H-T but it's hard when you can't search for two letter words...
