Diff. lock switch conversion for '83 Ur Q

[Ben Swann]

I just swapped Dash, console, etc.  from an '87 4kq into my '83 Ur Q.   I need to do something with the Diff. lock, mainly because the origiinal is broken.  It may be fixable, but I have some newer diff. switch  and panels.

I'm looking for suggestiions and diagrams to help implement one from either the later 4000 Quattro, or possibly one from a Quantum Syncro.  Fitment is one issue, and how to hook them up is another.  Of course, as usual I'm trying too use what I have on hand unless there is some compelling reason not to.

One idea I'm toying with is mounting the one from QSW in the ashtray location of the console.  Since I have an analog guage pod mounted in the connsole, I don't see the 4kq one as the best opption, unless I can take it apart or cut it up so it fits inn an appropriate spot.

Anyway, I'm curious to see what others have done.  Also how do I convert fromo the 3 line setup in the '83 Urq, to the later which use 6 lines.

TIA
