I need help finding a pinout on a 94 pickup 4X4 22re ECU. I am trying to instal a Water Gas System and can not find correct O2 sensor wire going into ECU. Chiltons says Pink/green, but this wire dose not flucuate voltage like O2 should.

 

Here's one from AutoZone's site for 93-95 w/22RE: http://econtent.autozone.com:24991/z...52800610f8.gif

Here's the page I got it from in case you need others: http://www.autozone.com/shopping/rep...00c152800610de

Let us know how it goes with your Water4Gas system. It has been debated on here before: https://www.yotatech.com/forums/f116...-setup-142590/

I have this diagram, it is in Chilton. Thanks for the reply. I'm trying to find the pin out which actually shows the pins on ECU with there designated letter & # ie D1 (4WD-MT) O2 sensor. Once I get my ECU wired correctly and perform millage test I will post my findings.
