It's the idiot transplanting the XJR into the Mark 2 needing assistance again. We're ready to fire up the beast but can't locate 2 final hookups. I didn't pay any attention to where things go when disassembling the 2001 donor car because my wife has a 1999 that served well as a template - until now.

The first pic is the '99 bulkhead below the wiper motor where some ground leads and a multi-plug exit a horizontal metal conduit. The second pic is the same point on the '01 harness where the ground leads, a larger multi-plug and a second three-pronged multi-plug exit - it's that second multi-plug I can't identify.

The next pic is a mystery vacuum line. I've accounted for the line that comes off the right side of the blower and goes to what I think is a fuel pressure regulator. There's another takeoff on the left side of the intake manifold forward of the inter-cooler hoses that splits - one going to the EVAP canister purge valve and the other going nowhere at the moment. My wife's car has a throttle actuator (I assume for cruise control) that receives a vacuum line, plus some small plastic lines that feed some components next to the brake booster - my '01 has neither a throttle actuator nor the latter components. The manual shows a vacuum takeoff on what looks like the elbow below the throttle body, but I can't locate this on my engine. Any help will be much appreciated.

 

For that electrical, check this for reference....http://www.jagrepair.com/images/Auto.../jagxj1998.pdf
That vacuum line appears to be the MAP line, the thumb drive sized piece coming off the mount off the firewall behind the throttle body....the lead is under it. Very similar to this only upside down. Actually in pic 5 you can see a plate at about the 2 o'clock position coming off the firewall with a square hole in it, that is where my MAP is.

 

Problem solved - both the electrical and vacuum leads were for the MAP sensor, which was hiding and forgotten in the bottom of a parts bin. Many thanks, Highhorse.

 

I like simple solutions, now enjoy her.
