You take off the connection/connections of the cars battery and wait about 10min then connect it back. Not sure if you just do one or both though. But that is pretty much it. And what do you mean boost?

Exactly!!! You don't need to disconnect the battery terminals to reset the ECU...unless you want to keep losing your presets. Originally posted by princess4

On most cars, negative goes to the engine block for grounding.Originally posted by scottc25
