In order to remove and replace the transfer Case shift Motor - you have to spend some time getting it right.

1) remove the 3 bolts on the motor
2) remove the additional bolt on the tail
3) remove the wiring harness plug - we're going to get the old motor out so you can swap the wires somewhere other than under the truck..
4) remove the 2 plugs in the transfer case which have pigtails attached to the main motor harness plug
5) the last wire is a single wire - it comes directly out of the transfer case and does not have a plug on the case assoticated with it.
6) on the motor pigtail - you'll need to take a pair of needle nosed pliers and pull the red center core out so that you can pry the plastic tab away from the pin and pull it out from the backside of the connector.
7) having the center core out allows you to pry away the plastic tabs and pull the wires out the back - pull this tab out and then shift the plastic tabs away from the pins. In this picture you can see they are below the top set of pins and above the second set of pins from the top.
8) Pry the wire
coming out of the back of the transfer case which is all alone from the harness first - this will allow you to pull the old motor out and put it alongside the new. This makes the swap way easier.
9) here you go - just move them over one by one - pry the little plastic tab away, then pull straight out - the pins will look like the above - just move them over into the same position on the new Harness.

When you're done - just plug everything back together and make sure you put a bit of form-a-gasket sealant on there to keep dust and junk out. If it has been awhile since
your truck has been in 4 wheel drive , cycle it a few times in and out to lube it up again.
