i know you need a male cig lighter and a 9v battery


but does the positive go to the middle or the sides?

is it just a straight hookup?

I'm assuming you're making a device so that you can disconnect the cars battery and not worry about losing the ECU and other settings.

I've never build one of these before, just working on electronics knowledge here

Positive should go to the center pin, negative or ground would go to the clips on the outside edge.
