Yes! The wiring I used on the 2013 may be different on other years or models, as the heads up from Harlan says. I'm using the Gen 4 manual (downloaded in 2013), even as we speak, in trying to determine what I need to do on my new 2014 DS. In their example they use digital input pin # 30 as an example for a reverse signal. As far as I know now, it is an unused input on my 2014 but I still need to confirm that. As Burton states there are other unused digital inputs on the Sevcon. Any one of them can be used for the reverse input signal and programmed to recognize that command.
The advantage in using pin 19 on the 2013 was that it was wired to the MBB but was not being used, Harlan warns that may no longer be the case for 2014 and later. That existing connection provided a wired connector pin on the Sevcon to be able to cut and connect to the switch's reverse pin. However, with the other unused digital inputs not having wires on them already, presents the problem of how to get an appropriate crimp pin to wire and insert in the connector. I don't know where to find a supplier for the pin. Anybody know?
This time I will be using a momentary push-button switch, on the left bar, held down by my left thumb to keep it in reverse. When released it will go back to forward. This leaves all of the rest of my hand free to grip. Since there is little downside to accidentally putting it in reverse while moving forward (just causes regen slowing) I'm not concerned about an inadvertent actuation of the switch (like mistaking it for the horn button) while riding.

BTW - I've already experienced difficulty in pushing my 400 lb DS backward in soft terrain especially with an up-slope. I've almost dropped it a couple of times and I've only had it a couple of months.
This bike cries out for reverse capability!
