Locking the rear diff in high-range should have been a factory setting! I used it all the time with a DIY e-locker I had in another truck.
What would we do without Dan, huh?!
No, not really any complications. I ran my rear locked ALL day today out at Little Sahara sand dunes without any complications.Wait, pin 7 mod allows rear diff lock in high range too?
You can have the rear diff lock with or without the pin 7 mod in high also.
I thought there was much more complications with freeing up the f/r diff locks?
Once engaged, of course. Or do yours (F/R) engage at highway speed?

... all the pin-7 mod does is stop auto locking in low
...without the switch you have to be in low for the center to lock and therefore have to be in low to lock the R/F lockers/

well since you have the CDL switch currently your options are 3
high CDL open
high CDL locked
Low CDL locked
doing the Pin 7 mod will give you a fourth option
Low CDL open, gives you low with more maneuverability when the CDL is not needed, also allows you to use low on pavement without worrying about drive line windup (manuverign trailers and alike is a good example)
