Quick Sensor Question

[M_R_205 5 1 Cars]

Im replacing some fooked wiring on my XS and im not sure which is the coolant sensor for the dash gauge, is it the on on the front of the engine next to the coolant bleed screw, or under the dizzy on the right of the head?

 

When i connect each of them to the sensor, unless the engine is running they bot send the gauge to max... any ideas why?

 

Cheers

Paul.

The one on the top by the bleed screw is for the gauge. The one underneath the distributor is simply a switch which closes at a certain temperature (105 or 110 degrees or something) and turns on the STOP light on the dash.
