Yea, no problem. I just looked at the end of mine and thankfully, all the power cables are labeled so M1 Blue and M1 yellow got to one motor, etc. Let us know how you get on with it. I only grabbed one when I was in the local model shop last time because I thought it was neat having the 2 outputs, and at £30 it was well worth a try at some point. I've never run mine yet though.
