There are two wires that go along the front of the motor, then wind down toward the spark plug area.

I tried to highlight the two wires in red down below...





One wire has a HUGE connector, then the other one is a singe black connector, what appears to be a ground.

Where does that single groud connect??

Not for the knock sensor, not the a/c or power steering, not for the oil pressure...

Can U zoom me in I'm not sure. THe small one might being going to the oil pressure sender. The larger one, I can't remember off the top of my head.

The small wire isn't going to the oil pressure sensor... It's got a plug-type connector.

I don't have another pic to really show what i'm talking about offhand...

where's JONSKI - he always has all the close-up under-hood pics...

If one heads south from there, its going to the crank angle sensors; but with that pic its hard to tell.

Not the crank angle sensor wires - those drop down behind the vacuum chamber.

The wires I'm referring to go underneath the oil filler neck and then the single ground connectior comes out and should terminate [or connect] down around the spark plugs somewhere...

I'll try to get a better pic... and i'm, trying to find it in the wiring manual as well......

You may be talking about the connector for the knock sensor

nope - not the knock sensor.

I believe it's the other ground for the coolant level sensor - there's the obvious one on the front of the t-stat housing, but from what I understand, there is another ground that terminates near the coil pack.....
