I just spent a bunch of time altering my wiring to now include a polarity switch. None of the wires would reach it so it turned into more work. Shouldn't have been a big deal but I hate wiring.
All of this because so far, I can't find a PS3 kit. I went to the MTH site and downloaded the sound file for an engine that listed having PS2. I swear the description says it's for a PS3? (4meg?)
I may have to upload the file from my older PS2 Evo w/ charging lights to use in the board. Maybe they all came with PS3??? Maybe I'll just borrow that engine's boards?
I sure hope I can find a kit before I finish building. That may take me some time though.
