      I know it has been discussed numerous times and I have read all the threads on it but some things are still unclear to me. First of all where is the BEST place to hook in the switch. Underneath the seat or behind the radio? And second where do you hook up the ground wire from the switch?

      Hi and welcome... I understand the clarity issue :D . The BW mod has taken on a life of its own over time.

      I would say anyhere from the left side of the radio (after the splice as GIJoecam mentions here:http://www.explorerforum.com/forums/showthread.php?p=1189714#post1189714) to the transfer case will work since it's a straight run between these 2 points. This would include under the seat. Just don't hook it up to the right side of the radio (before gIjoe's 'splice') as many (myself included) have done in the past.

      Any place you can ground the switch to the chassis will suffice.

      so just cut the brown wire under the seat put in a switch and ground it to the bare floor somewhere and i dont have to worry about putting it in between all of these splices

      I inserted my switch. Meaning, cut the brown wire, spliced in a few lengths and put the switch in my center console. and then back again.

      All the brown wire does is cuts the power to your transfer case. With the switch off, you have 2wd only. When you turn it on, you can then use your electronic switches on the dashboard to engage 4x4. The mod is mainly for people who have auto4x4 and don't want that for whatever reason. AWD is not electrical though, I believe it's mechanical. The brown wire probably isn't even present on an AWD explorer.

      The downside to this is when people use it to do too many burnouts -- the difference in the speed between the two driveshafts increases the oil's temperature and eventually kills the internals. There have been a few threads about this happening to people.

      Success rate is pretty much 100% -- i mean the only way it could fail is if you cut the wrong wire ;). Or you cut the wrong wire, flip the switch, and out comes a banaphone from the glovebox -- actually that wouldn't be a failure, that'd be a 200% success rate, forget 2HI/4HI, i'd rather have a banaphone :thumbsup:.

      just to reinerate
      BWM ONLY if you have auto 4WD.

      If you have 2wd then the BWM is pretty much useless. ( and rather silly)

      If you have AWD then you cant do it.

      No. Cutting the power cuts off the power to the front drive shaft.

      The V6 Ex's have the BW4405 t-case which has A4wd-4hi-4lo. Auto4wd is basically 2wd until the speed sensors on the transfer case sense a difference in speed between the front and rear drive shafts(such as the rear wheels starting to spin in snow etc.) then the clutch in the case engages and sends varying amounts of power to the front wheels until the speed of both shafts are the same. The V8 Ex's have the BW4404 t-case which is AWD, no ranges to switch. Power and torque to front and rear drive shafts all of the time. V6 equipped trucks have the range selector switch to the left of the radio on the radio trim, and the V8's have no switch.

      So, sounds like the V6 has a better set up for off road.

      In it's stock form, yes. A lot of people with the V8's have swapped in a 4406 t-case from the F-150's to get the same setup as the V6 Ex's. And you can tweak the V6 setup as well. Check out my swap thread in my signature.
