------------I believe that Scott J. did an "electrical" conversion of the diff. lock actuators a few yrs. back.   Maybe he or someone has posted to the archives . I don't  remember any details .        ... HT      ...Stephen '85Urq

  I will likely go with the mechanical route for now, ease and simplicity.  Then
  someday if I ever got caught up(HaHa) I could make the conversion to

  Now to do the diff lock conversion!

  Ben, I just went and looked at a spare sender I have, and the part that 
  mates to the tranny looks for all the world just like the business end 
  of a cable to drive a mechanical speedo.

  So look at your parts carefully, you might just be able to attach your 
  cable system to your new tranny, plug'n'play, as they say.

  I don't know how broadly my observation would apply across models and 
  years, but it certainly makes sense from a type 85 perspective - I know 
  I have an 86 "non-electronic" tranny in my 87.5 cgt driving the 
  electronic sender.  IE, they used the same trannies for both mech. and 
  elec. speedo setups.

  If you are going to get more adventurous... you'd need the wiring 
  diagram, of course, and a few parts, but you could get a cgt/urq 
  electronic dash and install it (mostly the same wires, different plug), 
  along with new wires to the speedo sender.
