Thread: What is this plug at the end of the injector harness

On a b13 towards the passenger side
I cant remember if its been hooked up or not, but its surely not now as the wire broke off the block, and i ripped off the tape and the wire was already broke in the back of it more also
here is a horrible cell pic. You can see the stray wire strands in the back and this is the plug

that i believe is for your knock sensor

no the knock sensor has the metal clip on it and is black with 1 wire. That looks like the connection from one harness to the other harness and is needed most definitely.

thats not on the injector harness. the injector harness only has four plugs for the injectors and a knock sensor plug with a metal clip. what are the wire colors and what else is on the harness with the plug you need to identify?

Ok sorry bout the pics, this wire(appears to be a ground wire? its black with just a metal wire wrapped around a white wire i believe). Its not attatched to the harness but its with the injector harness(i hate taking over projects from other people)
anyway here is some better pics of the plug(thats connected to the other side of the harness that goes on the passenger side) and the bare wire(besides the rediculous amount of black residue thats the stickiest stuff ever. Let me know what you guys think, and/or let me know how to wire it back up the right way? the actually wire broke to close to the plug so i was just going to wire it directly to the other side and by pass the plugs. Let me know please

its for the knock sensor, TRUST.. an it IS commin out of the injector harness he's right..

i'd get that fixed..

the second pic is of the injector harness and the only other thing on it is the knock sensor. I can't tell what the other picture is.

Definitely looks like it has 2 wires, which (unless I missed something big) means it's not knock sensor. Can you confirm if it has one or two connections in that plug? There's too much "I believe" and not enough definitive information.

i dont believe, i KNOW.. go pull that wire on your car, start it up.. plug in some nissan data scan or conzult or whatever.. it will be showing a knock sensor code..

if thats the wire that comes out of the injector harness near the #1 cylinder injector plug it goes to the knock sensor.. not to mention i've looked over the fsm cause i wasnt sure what it was along time ago.. been there done that..

you dont need a knock sensor
