   Won't hurt the ECU as long as you pull the connector off and only jumper   
   to the correct wires. One is ground and one gets power, most however   
   have the ground connected so that the engine is also part of the ground   
   side. Hook power to the ground side and you will have an issue.   
      
   However as stated in the other comment, the more likely issue is low   
   refrigerant. If you want more info including wiring diagrams and testing   
   methods might I suggest 2CarPros.com. Enter in as much information as   
   you can about the vehicle.
