The 168 is a direct replacement to the atmega8 chip. It has more memory because the 8 ran out.

The opto is U9 and the transistor is Q1. If you have the board so your can read the writing, and the power connector on the left, U9's notch should be pointing downwards. The silver metal back of the transistor should be closest to the power wires.

Heres a picture.




The transistor is next to the white and yellow wires. The output on my controller is the brown wire, pin # 3. This is +12V when activated and shares a ground with pin # 2, the 12v battery negative that powers teh logic board.

See if any of this helps!!
