    Hi y'all it's me again. you know !
    I'm not sure yet? I hope I'm posting the right way, if not can someone let me know? Because I'm not sure yet!

    Anyways to the point on the inside of the front left fender in my SHO I believe is where the EGR vacuum regulator assembly is. It's got two vacuum hoses going to it and two wires and my truoble is that I don't know witch wire gos where as there was some nice that had gotten into my vehicle and chewed up some wiring and I'm down to these last two wires and Im not sure yet which wire goes where I'd greatly appreciate any assistance.

    Man I hate them nieces to pieces!!!

    Thank you in advance

    Because I'm not sure yet!
    You know what I mean?

    Have a good day or night or BOTH.

    Ps I don't know how to add a tag or should I just say I'm not sure yet how to use or pick a tag!!

    I'll report to mods to combine this with the other new threads you made and move to engine subforum.

    You have a picture of the the EGR vacuum regulator solenoid. "EVR".

    The ports used shouldn't matter if you identify the correct hoses. However it is the centermost port that leads to the EGR valve. It opens and closes the vacuum supply from the intake which leads to the EGR valve. You should be able to follow vacuum line from the EGR valve's port to it. The EGR is on California emissions package cars.

    This and the DPFE sensor use brittle hard plastic vacuum lines. Green for EGR and red for DPFE.

    The electrical connector on a 92 uses a red wire, which is 12v power from the IRCM relay module, and a brown/pink wire, which is the command signal from PCM pin 33. You should be able to discover the connector somewhere, and wouldn't use wiring without it or without replacing the connector.

    If you do not have a dpfe sensor on the back of the intake with two hoses also, do not have an EGR valve, etc, it is possible that you have an engine or intake swap to one without EGR.
