Auxiliary Water Pump 2.6i Microbus

[Fang50]

I have a 98 Microbus 2.6i and seem to be having issues with my auxiliary water pump. From what I can tell it is relay driven and only comes on when the motor is really hot...this is to avoid any heat spots in the engine....mine started leaking and I am about to replace it....but my main issue is there is no power to the plug that pushes in the bottom.....I cannot seem to makout which relay it is...fuses seem fine...but before I replace it I would like to know that the circuit works well....

Regards
