99 100 series rear locker in High range?

[Auggies'Blu]

Dissagree on a 100 if the center diff is locked on pavement it will cause rapid failure of the front diff ,,,, see it all the time, the detail shop wipes down the dash and hits the swich and somehowe nobdy notices the lamp lit or the pull on the wheel,, next thing i am putting in a new diff,,,,good for me bad for cust,,,
above pic shows it all for what you need to do ,, only thing to add is to remove pin #10 from the connecter , the one for the speed signal, not necessary

This is definitely good to know! Thank you!
