    Hello fellow Toyota owners I’m new here. I have recently started a huge project on my Tundra. She started out as a plain Jane but after a few modifications she has turned into a beast . To start off with I raised the body 3 inches did a rough country 6 inch suspension did an add a leaf to the rear and 3 inch wheel spacers. Gave her both front and rear M1 Smittybuilt bumpers. I know stupid for 2wd. So here soes the project i have front diff transfer case both front and rear driveshafts and 4wd tranny which all i really needed was the housing extension and i have installed 4wd switch and control module . Now the problem I am having is no harness for transfer case and front differential does anyone know where i can get one or a diagram to make one. I assime that its built into the engine tranny harness as the hook ups are the same on both 4x4 and 2wd transmissions. Thanks for any help you can Share

    Check the build link in my signature.
    Welcome from the wet side of WA

    Check my signature for a link to the wiring diagram thread. You’ll have some investigating and some cross-checking to do, but most of the info should be there

    How's your project coming along? I've got an '07 SR5 and have been thinking of doing a 2wd->4wd conversion as well. Would help a lot on these snow covered Michigan U.P. roads.

    Any luck making this happen? I’d love to convert mine. Pretty sure it would be less than finding a comparable 4wd right now.
