The 4wd was a little more complicated. Not technically but mechanically. Im gonna try and explain as best as i can but i did this mod awhile ago and might forget a few things. Ok, remove the tray in the middle of the counsel. Remove the screw exposed after the tray is removed. The dash can just be unclipped after that. Remove the wiring harnesses for ac, passenger airbag light etc. The lower center dash has 2 screws if i remember correctly. Just pull the dash piece forward a bit, unclip the wiring, then unscrew the four screws in the 4wd selector. This one is also held together with clips but be CAREFUL! There are a couple small pieces that you DONT want to lose (like the contact thing with the prongs on it)! There was a spring and ball bearing in the dial assembly so open it slowly and while your working on the board, you might even wanna put that half in a ziploc bag or something. When i did the window controls, the spring and ball bearing went flying all of a sudden and i spent an hour looking for them! The dial should have the spring/ball, and the contact that tells the computer what gear to put the truck in. If you can keep that half in one piece youll save yourself a lot of headaches when reassembling. You can see the LEDs in the pic. Think there was only four. Same old routine, desolder, solder, test the LEDs, reassemble, THEN test the unit itself. Dont hook it up to the truck at first and check if you have any problems putting it in 4hi, 4lo, then back to 2wd. If it works fine hook it up to the truck and test it out again, this time with the truck running. Just take your time with this one and try to remember the placement of all the components.
