Please help. Which 10amp slot (that is only on when ignition is on) can I use for the add-a-circuit? I want to power my AEM wideband. The one I picked tonight had power all the time. Thanks!
Just probe with a test light when key is off. Then check the ones again when key is on.
Or look in the owners manual for a circuit that you know only comes on with key on. I cannot remember which one I used, and it is a bitch to get under there with seat in.
