yes but on the pcm side of the connector but there is 4 wires a blue white and 2 blacks. I know I need the 5 volt return but I dont have a volt meter to know what wire it is?

Yes I know it will knock maybe knock is the wrong word I'm not sure if its Detonation; Knock; Ping; Pre-igintion. I just know it doesn't sound right and I would like to know what my mixture looks like when using the nitrous.

Charles said not to mix and match jettings but I might, He said jets are only like 2 or 3 bucks each I was going to use my higher fuel jet for the 65 shot and use the 55 shot jets for nitrous.

yeah I pulled the lines of the nozzle and sprayed into a bottle for fuel and nitrous, I also checked the side on the module marked fuel indeed had fuel coming out and same for the nitrous side.

I also had problems with intake backfires any Idea what caused that? Seems to have gone away on the 100 octane but at 7 bucks a gallon on a daily driver isnt going to go over well lol

Thanks for your input mazdamaniac but I didnt try high octane to make it run "better" I tried 100 octane because it is guaranteed not to have any ethnol in it and I live in kansas so ethanol concerned me with my nitrous not working well.

You mean the rear O2 sensor signal wire?
What are you going to use that for? It won't return any useful information (not for tuning, at least) since its in the catalyst and its a narrow band.
Its not a "5v return wire", but the signal wire is yellow. Its pin 2Q on the PCM.
The red and white/red wires are the heater and the brown wire is power from the PCM.
The output is up to 1 volt - .55v is stoich. Anything that is not .55 is useless information.

I know its not a vary useful instrument for measuring the af ratio but no one cant figure out why it still knocks so I’m trying to find out if its truly a lean condition even if I cant find out just how lean it is or if its a bad zex module or failing coils? I believe there is a front 02 sensor not in the cat that I was planning to hook up to the colors you mention in the last post are on the pcm side of the connector any reason why you aren’t supposed to hook up on the 02 sensor side? Thanks for your help
