Diff lock on upfitter

[ogdobber]

So I’m adding more upfitters and going to have a couple extra so I was thinking of using one to control the diff lock (10 mph is waaay to slow)
Anyone know what activates it? 12v? 5v? Is it just grounded? I’m thinking it probably is 12v.
Btw This is the additional upfitters
