Wideband wiring
In my stupidity, I know I wired my wideband wrong. I have just power (red), ground (black) and signal (white) wires going to the ms3 pnp. Can someone please tell me the proper pins to use?

Your wideband is likely pulling more than 0.5A (assuming you're trying to run power from pin J). You need to run the power and ground to somewhere on the car rather than the MS3; I used the cigarette lighter circuit. Assuming your WBO2 is an analog signal, you can use either pin C or D, and set up the config to read wherever you connect to.

I had the wideband wired to the ms3 because that's how the ms labs one was. I wired it to the cigarette lighter, pulled the ecu, and confirmed the white wire was on pin c. The gauge is an AEM 30-4110. I think I figured out my problem. I was using 1 amp fuses. They kept blowing. Put a 10 amp in and it looks OK. Now I have to unpin that damn red wire from the ecu, before it gets me into trouble. I hate crawling under the dash. It's 95 degrees out today.
