    The 4WD will have a connector that runs down to the Thermal Actuator, and one that goes to the floor shifter for the 4WD.. you would be better off finding one from a 2wd truck with an Auto tranny, however it can be from a C-series (2wd) truck (1500, 2500, 3500) with any motor V-6, 305 V-8 (5.0L), and 350 (5.7L). The connectors are the same for those motors. As LONG AS IT IS FROM AN AUTO TRANNY, or manual if you own a manual tranny. Basically it just has to come from a 2wd that has the same tranny that you have....
    And it is VERY easy.. oh and it has to be from a 1994 since that is the year they changed over to the 4L80E which has different connectors than the 700R4.
