Many thanks for pointing out the minor issues, and great call on the dremel usage. I'll post up if I figure out anything else when I get into it tomorrow.
Attention Dremel boys.... The connectors fit fine. When you first insert them the lip on the Land Cruiser side hangs up on the Depo connector. Simply tilt the Depo connector slightly as you are sliding it in so it slips past and what do you know - solid locked connection.
I bought some 'upgrade' Sylvania bulbs as I assumed they headlights wouldn't come with any. Never installed them though as I thought the output from the Depo's was much better than stock anyway. Maybe I should give them a shot...
I dropped some Silverstar Ultras in there and while they aren't anything like the HIDs in my wife GS460, they're appreciably brighter / whiter than the stock bulbs that came in them.
