CANT FIND LOCATION OF PLUG IN ENGINE BAY, PLEASE HELP!!!!!!

[madxman21]

Okay, to recap, bought a 1993 300zx 2 weeks ago. Car had a hard start. Took it to the dealer and dealer stated fuel injector bank #4 and #6 was leaking. Dad changed the fuel injector and as hes putting the engine back together we cannot find the location of the white plug. The cord is short so it wont go any farther. Car no longer has a hard start, but car shutters like its about to shut off and check engine light is on because that particular sensor is not plugged in. Where is the location of the plug in?

Someone please help!!!

That plug with the white sheath is for your O2 sensor on the driver's side most likely, and plugs into an equally short plug of the same type right about where it is.
I can assume you may have plugged the EGR plug or even #6 coil plug mistakenly, re-check your connections and you can use the handy online service manual in the stickies at the top of the Z32 page for locations and diagrams.

That should not be your O2. That should be the VCT wiring plug and you should find the detonation sensor harness near by too. The white cable drops right behind and below the plenum. The opposite end of those should be coming from the DS and wrap around to the back. So the side on your pic is to the sensor itself. The side you can't find is the cars harness. That's what should be running along the driver side of the motor and wraps around the back.
