ST165 code 54 fix (I searched)

Well When I got the car it came without the inter cooler and the motor was in pieces. So I did a front mount and have CEL code 54. I ready every post that I could find on this issue, but none were able to tell me what exactly I need to do. Do I have to go to the ECU? Can I just do it from the plugs that used to plug into the pump and level indicator? Do you ground it like some say or do you put a resistor in? What do these plugs look like?

Thanks guys,
K

One horizontal connector on top of one vertical. Plugs into the intercooler. Comes out of the harness with the coolant temp sensors around the coolant outlet elbow. Black plug. I dont have a picture though.

Should be the only unplugged two wire connector near the coolant elbow

Hope that helps

Best I have for now:



Sensor is the rubber black/gray plug on top of the IC, its wiring goes down to the harness above the water neck. If you need more, I'll get actual pics today when I'm poking around the car.
