I am trying to slim down my harness and came across these plugs and have no idea what they are for,



area under intake manifold? two black wires come out of this one





in the area on top of intake manifold. thick green wire, skinny black


Also would anybody be able to tell me with an aftermarket FPR and fuel pump,
would I need the OEM fuel pressure sensor on the left end of the manifold?

 

I was using a diagram from Mitchell, it doesnt seem to have these plugs on the diagram

 

Not sure if you have got an answer yet. The first picture is for the brakes. Plugs into the master cylinder. The second one could be a few things. Is the plug itself black or grey? If grey its for the ignition. You don't need the stock fpr stuff if you're going that route

 

Hey man thanks a lot!
The one plug now in question is grey,
I still have no idea what it is for? project has been on hold

 

looks like knock sensor?

 

where cound I find the Mitchell diagram???
