Faking signals to ECU pins to fix check engine light
I've done a turbo conversion and I'm now using a GTT ECU on my GT loom. I don't have the boost sensor or TCS so I get the check engine light. I've read about the way people use diodes/resistors to fake a signal to the correct ECU pins (e.g. secret squirrel trick). But how do you put a wire onto an ECU pin when there's no female connector in the ECU harness - just an empty hole?
