5 to 4 wire O2 wiring help.
I have a p28 in an VX and d15b vtec engine. The p28 uses a 4 wire O2 and the VX harness uses 5 wires. What color wire goes to what? Thanks.

yel/blk-A25 - 12 volt switch
org/blk-A6 - O2 heater ground
grn/wht - sensor ground
wht/red - O2 signal wire
run it directly to the ecu for faster convenience. hope that helps. if not. IM

There is an extra step for the VX, there is a wire that is in a different pin that you have to move. Here is some pics and directions on the repinning.
