LS 400 steering wheel is 1:1 for LX450? (1 Viewer)

[landcruiser3DP]

i have a bunch of threads printed out i need to find snd also some notes. but is LS400 steering wheel a one to one trade out for the LX450?
i need to do horn contacts and would like to do the steering wheel at the same time.
do i need any extra parts?
any cautions on this job?
THANKS
