ATS Kenworth Style Button Box

32 button box video:    • MAKE THIS BUTTON BOX | 32 FUNCTION w ENCODERS   Ignition switch wiring video:    • HOW TO WIRE IGNITION KEY + STARTER SWITCH ...   Some notes on how I built my button box for ATS/ETS2. A lot of the videos that I've seen on button boxes don't explain everything so I figured I'd post these notes to help anyone who might consider building a box like this but may be weary to try because they don't know a lot of the details. Please put any questions in the comments below and I will do my best to help you with anything that I can.
