My AMR4974 BBUS sounder is dead so looking to wire in a cheapo additional unit. The plan is to also put it to a less accessible spot.

Can anyone help me with which pin is which on the BBUS? Need to find the trigger wire for the new unit. It would be good to know rather than find out by trial and error. Happy to receive a PM. Cheers!
