What size is the oil pressure switch? I've got big hands, and I'm trying to find out what size wrench to wrap around it.

Also: Does it go right into the block or is there a 90 degree brass fitting?

It is in the back of the driver's side, behind the head.... it slants slightly to the pass side.. usually you will have to loosen up that bracket that has the 3 electrical units on it, and slip to side without disconnecting any.... almost directly behind the glow plug relay

right into the block.

behind the head, under the bracket holding harness, driver side, on 1994-1995.
under the air intake, close fuel filter manager, driver side on late 1996 and above (block 141, 506)...

Weird. Mine goes into a brass elbow-like fitting, then goes to the pass-side. I have the PMDCable extension on the way, but want to make sure I'm on solid footing when it gets here.

What prompted this was when I popped the connecter off of the OPS to do a relay, I popped the top of the sensor off too. Peh

I ended up getting some flex tubing, and attached a ground line (via a screw tapped into the fitting) for the ground. USPS decided I can't get my PMDCable extension until I sign for it.

Now, to top it off, I can't pass emissions due to failing the snap test. CDR, CDR grommet, boost solenoid, and air filter go in tomorrow. Then I retest.

This 6.5l has been more problematic then any other car I've owned. Peh.
