[urq] Diff lock mods?

[Mark J. Besso]

I'll second that since it was my 4KQ that Bob designed/built them for.  They
utilized the door lock solenoids from a GMC Jimmy (gasp!) and they never
failed to engage/disengage immediately; regardless of weather.

Thanks again, Bob.... I sure miss that car!

I made this mod to a 4000q some time ago, using electronic motor
solenoids. I then had 2 buttons on the steering wheel that engaged or
disengaged each one. They could be done independantly at that point. It
worked great!
