Hello people, i have just done a full rewire of my RS turbo (yep crazy) and am a little stuck with the coolant sensors on the rear inlet manifold, on the wiring diagrams it doesnt say which is which like the yellow one etc so just wondering which goes to which ECU. I know 1 goes to 1 ECU and one goes to the other which goes to which please ????

Hope you can help me thanks for your time
