Hi everyone, anyone got a wiring diagram for the above?? I know i've seen it on here somewhere before but have spent 4 hours searching and can't find it!

Any help would be much appreciated

There is no definitive diagram for the S50 lumps as far as I am aware..

There is one for the M50's in the M50 development thread

Thanks jhonno i knew i'd seen a wiring diagram of some sort once, didn't relise it was m50.
