I do. I know one wire is light blue and not sure about the other. the two they connect to are red and black. which one does the blue connect to?

Here is the wire diagram I will be using. https://dl.dropboxusercontent.com/u/90220402/SC.pdf First off I need to know what these wires go to. Meaning what sensor or component?

It starts on the passenger side behind the head somewhere and has 6 plugs for the injectors, wraps around the front of motor comes back toward the firewall on driverside. After the #6 injector only 2 very small wires are left.These 2 wires are the ones that connect to a red and a black wire that come from behind a plate on back of head or block. I don't know what it is.

This black/red wire. Is it the power wire to the injector from fuse 3?

it is a black wire and a red wire . They go behind a plate on back of motor .

I do not see any sensors that get a black wire and red wire. Can you get me some pictures?

Will the vehicle start?

Sorry but I just can not find these wires in the diagrams. I will opt out and remove myself from the post.

I know they are not for the injections . They come out of the injector harness and connect to the red wire and black wire in photos. My question is which wire goes to the red wire and which wire goes to the black wire ?

Show me a picture of the harness with out the editing

Ask Your Own Nissan Question

That red wire and black wire, does it go to the connector at the crank sensor? You are just wondering which wire connects to which to the crank sensor?

Ok.. Hang on. What I am going to do is tell you what wire goes where in the connector for the Crank Sensor. This way you can then look at the Red and Black wire to make the proper connection.
