Having ran ARB lockers in my TJ for a number of years, I'll admit that there are times when having lockers engaged in HI range is useful and sometimes necessary. Anyone that has spent time on the dunes or cinder fields, among other places, would probably agree that having lockers in HI range is a good thing.
If you are a Jeep Rubicon owner, you have most likely discovered that your lockers can only be engaged when the transfer case is in LO range and you are moving at 10 MPH or less. I've no doubt that the Jeep engineers did this for a good reason (hopefully safety was the first reason). But none the less, having the lockers available in HI range would be nice.
A friend of mine asked me to assist him in bypassing the locker switch functionality that requires the transfer case to be in LO range. While I helped, I managed to snap a couple of pictures so I could share the information here.
I suppose I should add that this may or may not cause a warranty issue (on a new vehicle) down the road since one is changing the design by doing this. It concerns some folks while others don't mind. I made the statement.....what you do is up to you.
I did some research on the net and found some information that I could use to help my friend. It looked easy enough to do but since he's not into wiring projects, he said he would watch and provide moral support.
The cover for the center dash section must be removed. Pry up the defroster grill to expose two screws that hold the dash cover in place. My friend had a dash bar (installed with his Toys by Troy sport bar) that made access a little difficult but we removed both screws none the less.
With the two screws removed at the top of the dash, the cover can be removed from the center dash section. There are two clips in the bottom corners but they are just a friction fit into a couple of holes.
Lift straight out and up just a bit and the cover should come free without too much effort. The lower panel that contains the locker switch must now be removed from the dash.
There are four screws securing the panel to the dash. Remove all four screws using a Phillips head screwdriver.
