Help! ERevo/Emaxx wiring issue

[JThiessen]

I'm converting my Revo to Electric, with a new Novak Super Duty XR ESC, and a good used set of motors (just until i get my brushless set up done).
The Instructions for the ESC label the yellow wire as positive and the blue as negative. On both the Emaxx I took apart, and my running one, the red wire was soldered to the connector that had a small red dot beside it. I made the assumption that this was positive, and the other was negative. So I ran both reds to the yellow ESC wire and both blacks to the blue. And voila! I pull the trigger for forwards and I get full throttle reverse, with the slight brake release hesitation. Go to reverse and I get full throttle forward. I switched the throttle channel switch, and that only provided different speeds of reverse, and no forward. Whats the chance that the EVX wires are not necessarily red (+), and blue (-)? When rebuilding Emaxx's, its common to get the diff's flipped, and have problems because of that, but I made sure that it didnt happen here.

Any thoughts before I cut my power wires and switch them?:002:
