For Harley-Davidson models, pre-2011, 2012 use analog sig-
nal, 2012-up using digital signal. CAN bus system is based
on the digital signal. Analog signal runs by wire, so each com-
mands need wire to connect. For digital signals, each com-
mand goes to ECM, and ECM gives the proper reaction. This
is the basic idea, the real situation is more complicated.
