First I found that the 4th (D) string was quite low in relation to other strings. Looking at the saddles it appeared that the slot on 4 was wider than on 5 with 6 wider still - as expected. Prying the 4 and 5 saddles out of the bridge and reinstalling helped significantly.<br/>

The locking position of the vibrato was not in tune. Adjusting the Flat/Sharp could not change the setting far enough. I have 10s installed and it might want 11s or 12s? I found that filing the brass ramp down slightly fixed the issue. Going further would make it more adjustable, but right now I have it useable.<br/>

The tuners had a variety of issues - loose, tight, uneven. I removed and took the housing. Grease had hardened into a tar like substance. I cleaned that out and regreased with food grade grease. Tuners are now a little tight but consistent (probably crimped the tabs a little more than needed). Anyways - they work well now.<br/>

Wiring. I created a wiring diagram and attempted to characterize what the switch positions are doing:
