on your vxl it will have letters, A, B, C, and on most motors they have them on the end bell, when looking at the end of it, common lettering is left to right, a,b,c, so connect according, all the A's and B's, but if their is no letters on the motors, then any order will work and if it runs backwards you can up plug 2 wires and swap them around, but DO NOT do this if it is sensored motors, they have to be in order

hope it helps
