well first off welcome to the forums! to answer your questions:
1. the connectors are 3.5mm connectors available here.
2. the 3 motor wires are not directional. they can go in any configuration but i like mine to go in order where left to right match (you'll see what im talking about).
Thanks for the welcome and the help. The motor is going in my T4 to replace my ss5800. There is a chance I might put it in my RC10GT that i converted if my T4 starts breaking again. I think i fixed that though with some aluminum parts. I liked my converted GT alot for the durablity but it wasn't as fun to drive as the T4.
