Decided to hardwire this in the Mini but I'm too impatient to order the kit from Escort. Plus, their hardware kit comes with things I don't care about. I'm just going to tap in to the wires above the mini's maplights. That part is all set, now I just need to know which of the wires on the 4-wire connector are + and -,and which ones are only used for the 'smart cord' functionality.
