Losi Excelorin advice

[Hog]

Just picked up a 2nd hand Losi Excelorin, and it's missing the switch (which I did know about before I purchased). Holding the ESC so the PCB and switch / fan wires face you, the farthest 3 solder points on the left are for the switch. It looks like the 2nd and 3rd points have been soldered to eiminate the need for the switch.

My question - I have a spare Novak switch with only 2 wires which I want to solder to the Excelorin - which terminals do I solder to? I assume it's 2 & 3 (red & brown)? Is the 1st pin (orange) purely for the signal wire for the setup mode?

Might be easier to explain if you look at the pictures here http://www.oople.com/rc/photos/reviewlosixcelorin/

Thanks in advance.........
