 I ordered this small amp and want to check where the single pin signal lead from the TBS should hook up to?

Power input seems to be on two outer pins. The inner pins for signal input. What pin or pins would the TBS attach to?

I think you will have to refer to the Benedini manual for that, or ask over on RCTankWarfare where there seem to be more people who use the Benedini.
