Befor I got my RA I had an Apex so I modded the jebao to work with the Apex. In doing so I cut the wall wart plug thar hooked to the jebao controller. So now I need to solder the jebao wall wart cable to the RA cable pcb . My issue is not knowing weather the jebao cable is center + outer - or center - and outer +. Also what's + and - on the pcb.

Thanks
Dustin
