R3T - accessories socket, where do you get a plug?

There is a two pin accessoroes socket wired in and located behind the RHS cover of my R3T.

Does anyone know where you can get a matching plug so that it can be used. I was going to use it for my Garmin GPS. If I can get a plug it will save mucking around with wiring.

Thanks...

I got one from Walmart, they have several adapters in there parts dept. I also use mine for the Garmin GPS
