ECU pin 34 goes to pin 1 on ISCV, this is the PWM switching wire to the ISCV, pin 2 on the ISCV gets a constant live feed from t87 of the fuel pump relay.

Pin 20 on the ECU is the ECU power, which is supplied from t87 on the ECU relay (next to the fuel pump relay).

ECU pin 31 goes to pin 2 on Air Temp Sensor (ATS), ECU pin 11 goes to pin 1 on ATS. ECU pin 11 is a common ground return and connects to the ATS, TPS, MAP, & ECT.
