    Hey everyone, so I have a plug and am unsure where the thing goes. Just got my motor put back in(motor has been in and out a couple times) and I'm stumped. I have a 1g in a 2g so this very well may be an unused 2g plug but I like to know what things go to. I looked over the 2g engine harness article and this plug is not pictured . I've looked up various sensor plugs(cam, crank, etc) and none look like this one. It is at the end of the harness, after the injectors and coil pack plugs. Anyone happen to know what this plug is? Wire colors are Light green with black stripe and the other is red. IMG_0358[1].JPG IMG_0359[1].JPG

    if the wires are
    (red)
    (light green/black)

    its for the evap.emissions purge solenoid valve

    if they are
    (green/orange)
    (white/green)

    its for the dual pressure switch (A/C)

    I looked up the purge solenoid for my year and its not the same as this plug. I went through the 2g engine electrical connection article again and the evap purge is marked as number 27 but the plug is not the same as the plug I pictured. I know that article was based off a 99 gsx, mine is a 98 gst, could they have changed connectors? Thanks for the help I appreciate it! I just cant have connectors laying around that I don't at least understand where/what they're for :(

    I did a little more research and came across an article where the guy had ordered a evap purge solenoid and its the one on the firewall but it was not what he needed, he mentioned another but you can't find it unless you search for the Evap emission vent solenoid. That plug does look like what I've got :hellyeah:
