I'm looking for the wiring diagram for the 95-97 front o2 sensor.. There are 3 wires on it. A red, a white, and a black. On my older B15 sensor, there's two whites and a black. I can't figure this out!! Does anyone know what the configuration of those 3 wires for the B14 are?? On my other harness, There's a 12volt constant(white) and the other 2 show fluctuating minimal voltages. Which one on the B14 sensor needs 12 volts constant? Thanks for the help!

I'll look at my FSM when I get home and PM you.

TTT

I have a 95-97 FSM...


For the front 02 sensor it says there are 3 wires, but different colors. :confused:


[1][2][3] <---thats the connector view


1) Orange, goes to pin 115 on ECM (02HF)
2) White, goes to pin 46 on ECM (02SF)
3) Brown/Yellow, goes to ignition (guess thats what your looking for)

BTW that might be the view of the harness connector (not the actual 02 connector)


So it may be [3][2][1] looking at the 02 connector

BINGO! That's what I was looking for! I actually stayed up on the phone with JCGator42 last night till about 1am figuring this thing out. It turned out that I had a bad pin in the connector and it wasn't making contact. lol...fixed that and voila! Thanks for the help though.. MUCHO apreciated!

No problem... so is everything running smooth for you now?

yeah...It's running great! It's still running kinda rich though. I don't know what to look for now. Idles smooth and pulls VERY hard now at 9psi of boost with a 60 trim T3. Any pointers as far as what to double check. I'm pulling 17" of vacuum at 750rpm. I had to adjust my idle air control valve b/c it wouldn't stay running. I did have an air leak before though. Could the ECU have adapted to that air leak? And when I plugged that hole I would have needed to open the idle air valve a little more? Other than that...smooth sailing! Man..the car feels fast a hell! I can't wait to go get some runs in..

Like I said stick with it. I told you it was just something small. I am happy you are up and running. Good Luck.

Hey Andreas.... I want to thank you again for all the help you've given! The new injectors are great! Smooth idle FINALY! I'm sending that fuel rail next day air to you in the morning.. I've been tied up trying to get this thing running. Hopefully nothing else goes wrong...

Hey Travis

iam happy to see you got the car runing better/ sorry i didnt get back to you much faster i was in Houston all week then up to Dallas for the texas rally. plus i have put my fsm some where and now i cant find it wich suck big time.
