Dont know if you are still here or not, but.............
it is 5 years later and I've purchased a 93 Ls 400 with the original 66,000 miles. Got a new key and ROM from lexus, they wanted to charge me an extra $120 to install. They had aleady got me for about $800 the same day. Needless to say, I've been looking for this information for a while and low and behold -you -like a '5 year old blessing'! The pics are just what I needed -- THANKS!!!!!
If by chance ,(as I suspect), you are no longer a member -Thank you to anyone who reads and responds!
