I'll jump in and try to clairify things a bit.
I had never had an occasion to look at the LX450 harness part numbers so I peeked at that catalog.
Here is the skinny:
ALL US LX450's use the same floor harness that travels down the left sill. It makes no difference if the vehicle has diff locks. ALL years of 80 series have D/L and non D/L versions of that harness.
So, converting a 450 would only require building a short harness to go from the rear axle harness up into the quarter panel as opposed to going all the way to the cowel as required for an 80.
It is not a complete plug in unless the rear sill harness is also changed as that harness contains the ground path for the locker and makes the bridge between the axle wire and the floor wire.
