tarbe said:You do the pin 7 mod in conjuction with adding a center diff lock switch.
The center diff is only on when you depress the CDL switch.
Pin 7 allows you to run low range without the center diff locked, or to lock the center diff in high range.
If you do pin 7 without a CDL switch, you will never have the center diff locked (or your front/rear lockers if you have them).
And, there is already a plug prewired into the truck behind the dash, just waiting for you to put the switch in.
