To sum up the thread.
Brown wire mod: all this does is kill the power from the computer to the clutches, so that it will not engage the awd or a4wd. There still is power being applied from the transfer case to the front end, but not enough to do anything. There should not be any front wheel pull when the truck is on the ground. With a switch installed. There is total control with out getting out to put in hubs, or replace a fuse.
Hubs (manual or automatic) driveline pull: If you can find a set of hubs for our trucks. All these do is disengage at the wheel. NOT THE TRANSFER CASE. the complete front axle assembly will still turn. At this point you have MPG loss due to having to pull the system To pull the drive line. There is quite a bit of work to get it done. then there is installing it when it is needed again. For me. I like to have the front drive line there. even if it is just turning and not really doing anything.
pulling the fuse: ALL THIS DOES IS COMPLETELY DISENGAGE THE TRANSFER CASE. YOU WILL NOT HAVE ANY 4WD HI OR LO. ONLY 2WD. This just kills the power to and from the case.
I feel it would be a better deal to install a switch to the brown wire, then to anything else. It does not seem to be very difficult. It can be done under the car with out removing to much. The choice is there to just cut and cap, remove, or install a switch. keeping in mind that when the truck is off the ground. The front tires will turn. The system will still turn when driving. But their will be not be enough to turn the tires. I would assume that this can or could wear out the magnetic/electric clutches for the awd drive with slippage. I can not say for sure. just seems logical that something there would wear with the brown wire cut.
I have not done this to mine yet. I have pulled the fuse for research. I will attempting to this mod this weekend. I will to a full write up with pics and post it up for everyone on Monday..
I hope this helps future readers. Sometimes it helps to have all sides listed on one page to read or understand.
