Hello I got this setup to get me going on a budget in my 4x4sc, NOW i got it in and am just looking at 2 things, the wiring from the ESC to the motor. there isnt any labels on them as to which spot they plug into on the ESC...

secondly i am going to start at a 14 tooth pinion, how do i check/ verify that i am too many or too few theeth on the pinion
THANKS all for your help
