The pictures posted in reverse order. I took some reference shots and then close ups. I hope this helps you.

Artur,
Looking at the pictures again, I want to add that the top red and black wires go to the cab headlight. If you need more let me know and I will try to get a pic of what you need.

Artur, Looking at the pictures again, I want to add that the top red and black wires go to the cab headlight. If you need more let me know and I will try to get a pic of what you need. Looking at the board the plug on the end in front of the chip has outputs for: Red & Black - Lights Orange & Blue - Speaker The plug next to the cap on the other end of the board has: Black & Green - Left pickup Black & Red - Motor Yellow & Brown - Right pickup The two wires soldered to the board are for the cab light LED. How are the headlights connected and do they wire directly to the LED's? Thanks again for the help.

Artur,
From what I can see in the pics the hood end of the board has track pick up with:
Teal and brown from the hood end truck
Black and yellow from the cab end
The red and black wires in the center I am not sure about.
The cab end board I think has:
Orange and blue for the motor
Red and black might go to the speaker
If you can give me a couple of days I will try to crack it open again and draw a diagram and then post it. Might be Monday or so before I get a chance.

I took the MP15 apart today and traced all the wiring. The wiring in this model is jumbled beyond belief! I really thought of rewiring it, so many spliced wires. So here is the drawing I made of the wiring: I hope this helps out.

Artur,
Looking at the diagram, I made one mistake. The black pickup wire beside the teal wire is right side pickup not left.

Artur,
Thanks for redrawing that schematic! I am no artist and don't even have a drawing program on my computer, not a skill of mine. If you go back and look at the pictures, the wire color changed on several wires. I am not sure if this is factory on not. If not it is a very professional job. There are a few splices I would not have if I had done this install.
