i have a 95 toyota celica st with a JDM 7afe ecu and wiring harness.

what i need to know is im putting on a aftermarket exhaust and it only has one hole for the first o2, i would like to reprogram the ecu so i can delete the second o2 but i cant find a programer on ebay please help thanks

Just don't use it. It's either on or off , if it throws the cat convertor light just ground it out but I'm sure it just stays unplugged

it wont throw a code on a 95

it will on a 96.....

that's because you have obdII

I'm told JDM Toyotas don't have OBD at all, I tried to get an OBD cable for my 1996 JDM ST205 i'm told the diagnostic port looks nothing like OBD I or II...

Anyways, what I first said still stands, that sensor is unnecessary on a JDM. If it's throwing any lights or codes, ground it out or otherwise unground it, it's either one or the other.
