Identify this plug? (SR20det)

[Stamina]

I'm putting my sr back in and have one wire i cant find where it plugs into. It is located at the top buy the fuel rail, it had the exact same connector as the ones that plugs into the injectors (rounded square with a half circle notch on the end). There are 5 in a row, 4 go into the injectors and this last one is at the end of the fuel rail/valve cover close to the firewall. I cant seem to see where it goes and me and my buddy were thinking it was a dummy plug??

Could anyone take a look at their sr to see if they have similar??

Thanks :goyou:

A picture would be helpful. Plugs you need near the firewall by the intake manifold:

knock sensor: 2 pin gray plug
IACV 4 pin (3 used) gray plug
Coil packs 4 pin large gray plug
o2 (should obviously be much longer): 3 pin brown plug

Yeah i know a pic will be very helpful. If i dont figure it out by tonite i'll get one up tomorrow. I didnt have my camera lastnite.

Thanks for the info statik.

does it run?

i know there is def an extra plug for factory purposes. i believe for adjusting timing instead of tapping into a wire on the coil packs, nissan uses that plug.
