nope the computer wont recognize just the switch i.e. it wont engage the locker in 2wd. So you'd need the module. Silly I know, you would think it'd just be a power wire ran straight to a relay to power the locker and a light on the dash but thats not the case. You could also just hot wire the locker up to a switch on the dash and get locker use in 2wd that way. Plus you wouldn't have any of the other limitations of the stock switch. You would I believe lose the light on the dash though.
