I’ve had a ton of help from people on here. Wanted to ask how I can properly back probe on the ecu harness. Below it says to check the E10 wire harness. Specifically on this harness it saying to back probe on pins 31/29 and also pins 22/29. My question is which of these pins does the positive and negative connect to from my multimeter? I’d assume the negative connect to 29 only, and positive can interchange from 31 and 22 while keeping negative on 29 the whole time? Do I got that right guys? And do I just test with the ignition on not the engine running?
