SDS100/SDS200: Uniden SDS100 GPS Power Cable (Uniden BC-SGPS)

[OutlawPilot]

I want to hard wire the power to the Uniden BC-SGPS GPS unit (which will in turn also power the scanner). I'd like to keep the existing 12v automotive power cable rather than cutting it up to hard wire. Does anyone know the barrel connector size for the GPS? Or suggest a suitable USB or bare wire cable for the GPS?
