instruction says to mount the Crankshaft Position Sensor CMPS on the plate that the throttle body sits on. I do not see any clip for that.

 

CMPS is CAMSHAFT POSITION SENSOR.
CKPS is crankshaft position sensor.

 

yes I meant camshaft

 

I'm a little confused. On the two cars (XKs) that I've worked on the position sensor was mounted under the engine and trans in a little mounting hole on the front side of the bell housing. Then, the wire ran (from memory) forward (towards the front of the car) to join into a larger wiring harness that came up the LH side of the engine...

Are you talking about cam shaft position sensors?

 

The CMPS is mounted in the rear of the cylinder head.
The harness CONNECTOR has a mount tab that fits into a bracket you are describing.

 

yes CMPS and my throttle body does not have the tabs to connect. I am going to get them from a junker

 

Most of those mount tabs were never transferred to a NEW/REPLACEMENT throttle assy during repair.
Throttle problems were common when I worked at the dealer during that time.
