Wiring was a piece of cake. In the wiring harness that goes to the control pad, there's a Green wire, a Brown wire, and a Yellow wire. At rest, none of these are connected to each other. For Accel/Resume, connect Brown to Yellow; and for Set/Coast connect Brown to Green. In other words, connect the Brown wire to the switch's center terminal, Green to the upper terminal, and Yellow to the lower terminal. I ran the wires inside the existing loom that runs up to the left switch cluster, so no new wires are visible. The other wires in the control pad harness are not used. I also connected the Brown wire to the Red wire (at the servo unit) in order to put 12VDC onto the Brown wire, although I'm not sure I had to do that.
