Hi Wayne-
I believe that should be a non-turbocharged 567.
Thanks
Matt

Nothing like a show to get one's ass in gear ;D. Took the shell off and getting ready to do 1st install. I purchases a TSU-1000 and a 810129 23mm Mega Bass Speaker. Struggling with the install. the instructions say to install the 2 purple wires to the speaker. But dont know which wire is + and - for for the decoder or speaker  . Does it matter? |

As far as polarity goes, you can go either way. Speakers and light bulbs don't care which way the power comes in, they work either way.
That said, if you crosswire two speakers, they will still work just fine. No complaints from them at all. But, the sound will take a hit, because the two speakers will be out of phase with each other, and one speaker will create sound waves that will be exactly opposite of the sound waves coming from the other speaker. This effect causes the sound coming from the speakers to be very muted.
To avoid wiring the speakers this way, there is a positive and negative on some of the speakers, so that if you are wiring multiple speakers together, you can avoid this problem. Most of the time, we are lucky to get one speaker in the loco, nevermind two.
For a single unit install, as has been mentioned before, you'll be fine to wire the speaker to whatever wire you wish.
