Couple of things.
First, once you get this thing working, please note that according to the setup guide, this thing is good for up to a 12T brushed motor. So, your 10T motor is too hot for this ESC.
Second, the instructions show a "y" wiring method. Assuming by the "Tamiya method" you mean that your battery has a plug on it, I would wire it using the "y" method. Fig. 6 on the manual shows this. If you have a connector on your battery, you need to have the male version of the connector on the "y", instead of the wires soldered directly to the battery as shown in the figure. Hope that makes sense.
