Did a mini-me to my VX. Anyway its throwing code41 for the O2. The VX is 5wire and i need to know how to wire the 4wire into the harness, preferably so i can maybe use the pre-existing plug. Basically which wires correspond to which wires on the plug and also match with their locations on the end when it reaches the ecu. Any help or instructions would be greatly appreciated.

Also, going to check jyards for one, What similar car makes and models/years can i look for an o2 sensor off of? This would also help, on a shoestring budget so going to scour the local salvage places.

heh, come on, i know people like using the vx for its prewired vtec and weight, doesnt anyone remember how they dealt with the 5wire vs 4wire O2?

yel/blk - A25 - 12V switched
org/blk - A6 - O2 heater control
grn/wht - D22 - sensor ground
wht/red - D14 - O2 signal wire

Get a 4-wire o2 with a plug and find a 4 wire o2 plug off a ex/si harness. Then wire the wires according to the chart to the ecu. One of the wires changes color next to the ecu but the pin numbers are all correct.

I had to do it to my VX when I did my swap and this is the easiest way I found.
