Need wiring diagram for 9 pin Bose Speaker plug

[Aprisa]

I am playing about with a couple of systems that my sister gave me that were taken out of their house. I'm having problems with getting speakers connected to a PS321 system as it uses a 9 pin "printer" type plug which is not easily sourced in the UK.

Despite a lot of googling I cannot find a diagram that will enable me to cannibalise the new cable I have got from Maplins that I hope to use as an adaptor?

This is the cable and it fits fine just need to know which pins are +ve and -ve for the speakers L and R.

For reference that is a Serial Cable. Sorry, can't help with the pin outs for Bose. Do you have a test meter that does ohms? If so plug it in the amp and see which pins have a reading, should only be 4 pins, then put some music through the system and see which pairs have a voltage.

Thanks, I didn't even realise my car test meter did ohms!
Found out its 1 2, 4&5.
All wired and working.
