Update:
The AVL Classic has come along nicely (I figure 80% completed.), but I've run into a snag in the electrical.
All that's left is to deal with these two connectors, both 2-pin, and originally labeled for my convenience. Problem is I now have no connectors to match up to these. One is male, the other female, and both come out of what appears to be a gang box or power distributor. The long pigtail with the 2-pin connector is labeled "Multi A" referring to the box labeled "Multi", the other I simply labeled "Unknown" and it also comes from the box. So I got out the wiring diagram and...
MULTIPLE checks of the Wiring Diagram have left me stumped, as I simply cannot see this box anywhere in the damned thing! I'm either blind, a fool, or both but I could sure use a push in the right direction.
If I can get this done, all that's left is a to finish tidying up the wiring, install the seat, fire it up and go from there.
