I've posted some of this information in another thread, but am posting it here in full with photos for future reference.
This is to explain the 5 pin connections on this battery system:
As you can see from the case outline, pin 1 is nearest to the rear of the bike, pin 5 to the front.
Pins 1, 2 and 4 are used in charging:
Pin 1 is a charging monitor, presumably of temperature.
Pin 2 is the common negative connection.
Pin 4 is the charging positive connection.
Pins 2, 3 and 5 are employed when the the battery is mounted on the bike for use:
Pin 2 is the common negative.
Pin 3 is the battery charge state meter signal going to the handlebar meter.
Pin 5 is the output positive.
Therefore, when using another make of battery, connections for the two leads to the underside of the bike's battery platform are:
Positive connection to the platform pin position 5 nearest the front of the bike.
Negative connection to the platform pin position 2 nearest the rear of the bike.
The pin position 3 in between is redundant then.
