o2 sensor wire

Best would be to T splice into it at the ECU behind the passenger side kick panel. Don't have my diagram handy otherwise I'd let you in on exact location and exact color of wire.

I reccomend doing it at the ECU. The O2 sensor wire is shielded for interference and if you do it in the engine bay, you can get weird signals because of the spark and it will throw off the gauge.

does any one know wich wire off the ecu to run it. i know i have to run it from it but wich wire? if you run it right off the o2 sensor it will give you some really wack readings.

This is for an SR ECU, but I'm pretty sure that the standard KA is the same!It's number 29 on your ecu!It's the 5th wire in from the left, i believe, a white wire!Before you snip it, use a multi meter and do a resistance check between that wire and the wire connected to the 02 sensor!I'll email you the ecu diagram if you want it!my email is [email protected]Good Luck!
