Can you please tell me how to wire Pins 1 and 3 of my Bosch 3 pin idle control valve (Part no. 0 280 140 509) for my M800 install on my 88 BMW M3. The stock wiring is as follows: Pin 1 to Pin 34 of the ECU labled "idle speed control", Pin 2 to Pin 87 main relay, and Pin 3 to Pin 33 of the ECU also labled idle speed control. Thanks in advance!
Tom
