Hello my sr3 haven't anymore the connectors on the coolant sensor and I have standard sensor on hose.

I have too a used sensor 100 ohms I guess it's an original one from aim but have only 2 wires.

Can you help me to connect this sensor or the standard sensor I have? Because I don't know who to connect with who.

Thanks.

Hi I compared the wiring with the oil temp sensor and now i can say that:

wiring side of car           wirind side of sensor

yellow----------------------->Red

white------------------------>white

-brown---------------------->black

-green---------------------->blue

 

I learned too that:

The MXL Strada system doe snot support 2 wire sensor configurations.

The wirings that I have shared is not the conventional AIM wiring . 
 
 I will need to add a binder 719 connection to the car side harness to use the Pt100 sensor. If you are not going to add the binder connection then you will need to create a 2000 ohm pull up circuit to replicated the pull up circuit in our PT100 sensor connector before the hardware will work as expected.
