Wiring harness question

[Eyvind Spangen]

Car in question is a '90 200TQ. The after-run pump gets its power
through a fuse. This goes in a red/black wire to the pump, and then
continues to the temperature sensor. My question is: The wire from the
fuse box to the pump, does it go through the engine harness (the one
with all the sensor wires + injector cooling fan) or the left harness
(engine cooling fan etc.?)??

My problem is that this +12V wire is missing.. I only have a wire from
the temperature sensor to the pump, but it won't run without power..
