the lead in the first reply looks a good one to plug into your battery but i would cut off the tamiya plugs and fit some of these as the current drawn would better suit these plugs than the tamiya ones,
everybody uses these, (everyone i know in the 3 clubs i goto anyway)

and as you said your a newbee i gotta add the plugs with only one set of metal connectors pertruding from the red sheilding go on your battery and the ones with 2 sets of connectors petruding go onto your speed controller,
positive wire (red) goes to the square (biggest) connector on the plugs
