Been taking full advantage of my vacation... just completed my first LGB F-7 set to convert.
Each A unit has a DCS protosound board. The B-unit has been wired in using the exisiting wiring connectors and harnesses to pass track power and speaker sound from one of the A units. There is of course a slightly lower volume level on the A that drives both the A and B unit speakers. All three engines now have lights in the shell to shine light out the round windows on the side. The original B unit switch now turns those lights on and off. (same for the A units except they retained their original function) The B Unit also now has factory LGB wheel power pickups(I had a set of LGB brushes on hand). All three units now pass and share track power. The B unit can be oriented either way and still function properly/safely. The A unit that doesn't pass sound has its 4 wire connector removed off the back so there is no confusion on which A unit passes the sound. Each A unit has a volume potentiometer in the original hole provided and is a perfect fit.
This sound file didn't have the cab light circuit activated (it did have the loudest volume of the ones I tested which is why we selected it) so I left the cab light wired into the existing LGB light circuits. Decided to leave the number board lights wired into the LGB circuits.
Because of the motorblock design I did have to cut power to one axle on one truck on each engine. This was easily compensated for by adding weight over that truck. (less than 2 lbs)
Each A unit originally pulled 2 lbs in the initial pull tests and after being allowed to spin it's wheels a bit they scuffed up and the traction level jumped to about 4lbs. After conversion they still pull 4 lbs.... so actually the set can pull twice what it did when I got it. The weight is distributed such that both sets of trucks slip at the same time so it's properly load balanced.
Do note that the sound isn't quite as loud as it sounds in the video.

This set looks good in the warbonnet scheme.
