Installation was pretty straightforward, needing only a couple of new battery cables. The supplied data cable is VERY long, so I made up a new one using 3 pairs of some Cat5 cable. I asked customer support about the wiring, but never got a response.
Only real 'learing curve' was NOT to attach the charger to the battery terminals. Neg lead of the charger has to go the the other side of the shunt, otherwise the monitor doesn't know you're charging.
