Location is correct above, it will have 1 pin for the early type, 2 pins for the later "afterglow" GP relay.
Thanks alot. Will try to locate it tomorrow:-) you dont happen to know what i am going to do to get the stock w201 2.5diesel tachometer(measure RPM) to work with the six cylinder? I hooked up + to 12v. And the signal to the alternator. When i rev to max it only will go from 0 to about 500rpm. Looks like it misses another number.

Drivers side of the bellhousing about 2/3 of the way down. You get to it from the bottom but no lift required. Just ramps or jackstands.
thanks alot. I have now hooked up the water temp sensor and changed the thermostat, adapted the stock 300DT air filter box, made the w201 a silent killer
But.. I used atleast 1hour to "get all the air out" did all kind of things, unscrewd the tempsensor on top of the upper radiator hose housing, squized almoast every hose in the car. But the engine still runs about 100-105dgC. (thermostat -> 85dgC). Im out of ideas.. Maybe the water pump? the radiator is really cold, only the top of the radiator is maybe 1/2 of the cars temp. bottom is ice cold. Frightens me.. Do you have a answer to this ?
Edit: Using a Electric cooling fan with no brain, just a switch. And the heater
The stock setup uses an electric "auxiliary pump" which does a good job of pulling water/air through the head and heater core, pretty much self-purging with the heater on. Do you have this pump enabled?

It probably is "webasto", if I'm guessing the meaning of that right. It does not hook to the ignition, it gets switched on and off by the automatic climate control. Course you can just hook it to the ignition anyways, not sure how long it'd last on full duty though.
On my recent install I just hot-wired the aux pump before starting the engine to get the fluid pumping. You might be able to do the same with your Wabasto circulation pump.
