    Hello I have a 2003 Tundra (stepside model). My 4X4 switch has been flashing and found that the connector or wire harness has been chewed or cut by an animal or something. I've added new wire and crimped it. Worked for a little bit but eventually came out of crimp. I've run out of wire and I've been searching for the harness or connector as a whole. I cannot find the part number for it. It connects to the actuator as pictured below. Your help would be greatly appreciated. Inked4wd actuator harness.jpg

    On the truck, or the replacement parts? You’re not specifying which.

    @BubbaW or @FiatRunner is this a part number you guys have on-hand by chance? I know there's a link in reply #3 of this thread that shows how to find the part number, but I guess @flowe wasn't able to use that for the harness in the EPC under Electrics > Wiring & Clamp (I know the connector is a separate thing, I think that p/n is in the EWDs or FSM). I found a wire "differential wire" in mine, which I think may be it, and the harness is still availbable, but I've got an '06 vs. his '01 so I'm sure it's not a matching part.

    What Bubba said. Part 90980-11858, found on page 232 of the EWD, I've actually printed this page out because I've used it so many times.

    I also added the wiring diagram .pdf for a 2002, which should be the same as the 2003 for 4WD related stuff.
