On a PS2, 5V, GG1, these are the boards that control the bi-colored class lights and pantograph operation. Are there schematics available for these boards? Would like to adapt them into an ERR upgrade.

You are making a joke, right? 
I don't know of any MTH boards where the schematics are available. 
Your not going to be able to make it work with TMCC. The GG-1 has special flash code for the processor. It needs PS to work. G
The only way I can see to possibly make it work is to create a custom board that plugs into that driver board. You'd have to do some reverse engineering to see what can be done.
Thanks just the same, gents! I was hoping someone had already done the back engineering for me....a hand scribbled schematic would have sufficed. I'll bypass the idea for now.
