Yeah, it kicks out somewhere between 20 and 30 mph. You have a writeup on what you did?
My thinking was to take whatever circuit "deactivates" the locker, and make some kind of jumper. I assume there is some kind of "normally open" or "normally closed" switch that can be bypassed.
looked a little while for some wiring diagrams yesterday, but didn't find quite what i was looking for.
when i do this, i'll be sure to do a write-up. i was a moderator on another site, and did some tech articles a while back. haven't done one in awhile, should be fun
btw, used my locker about 6 times just on the way to work today. very wet weather here, and super-slick streets. TC off, locker on works great for taking off from stoplights without spinning (better than having the TC/one wheel peel practically stop me in the middle of the road)

I have been meaning to do my fx4 but since my diff started whining I think I will just put the Detroit locker I have had sitting on the shelf for almost a year now in it instead.

I did a small write up on it in the middle of anther thread, but it was like 60 page thread. I found an acc. wire under the dash and spliced into it and ran that wire to my switch. The wire that goes to the the rear end for the locker comes for the tccm and I think it is brown wire with purple stripe. Then ran a wire from the other side of my switch to the wire the goes to the rear end. I spliced into it where it comes right out of the tccm. It is in the kick panel passanger side. It is a pain because it is tight in there, but you can splice that wire in anywhere between the tccm and rear. I did mine there so it wasn't out in the weather. The diode gets wired in so when your switch is powered on it will not let the power go back to the tccm. I will see if I can finds some pics of it.

For those that are combing the forum for this as well, including the word "diode" in the search really narrowed down the results
