Rob, just saw your post about rebuilding the hyd on your 88. I&#039;ve never messed with one with the ele. switches on the steering shaft, only the ones with the levers coming out the top of the unit. Not much inside one of these lever units that can&#039;t be figured out with a little mechanical common sense.  I&#039;ve heard that the wiring harness for the electrical portion is somewhat expensive. The hyd. rebuilding tape you speak of   covers mostly rebuilding the pump and some on the valves. Don&#039;t remember anything being covered on the electrical part of it.  E-mail me if you have any more questions. oleblu
