location of coolant pump after run control unit

[tom]

Hi all,
    Doing some work on the 200 20vt and I've noticed that the after run pump and fan are not comming on even if I short the switch leads from under the intake on the coolant manifold. I have the Bentleys for the car, but they only show the current tracks etc. I need the location of the control unit, to troubleshoot, which Bentley calls out as J155. Found all of the fan relays ok but I haven't found the control unit on either of the relay panels. Is it buried somewhere? Any BTDT's ?
Thanks, Tom Nestor
