Meter display remains on at all times, the little hour-glass blinks when the motor is operating (if you wired it correctly and it's not broken). It remains to be seen how long it'll last being on all the time like it is, but as long as I write down the time every couple weeks or so I should be fine even if it dies. For a few bucks, it's not bad.
For installing the wire, I zip-tied one end parallel to the plug wire, made a 90-degree bend and wrapped it tight exactly 5 times (ending on the same side of the plug wire that I started on), made another 90-degree bend to get parallel again, then zip-tie tight so the coil doesn't get loose. Would have also put heat-shrink on at this point, but didn't have any big enough to fit over the boot that could also shrink to fit the wire.
After installing the coil, I simply routed the wire around the motor shroud, installed the meter on the wire where I wanted it mounted, then stuck it in place with some heavy-duty scotch 3m fasteners.
