It is on the transfer case on the top of the driver's side. Find the front driveshaft and follow it back. It will have three vacuum lines on it.

i found the front diff on the side towards the middle is where the driveshaft starts now there is this electrical connector there no vac hoses but i unplugged the wires and plugged them back in and have only the 2wd light when before at least i got some lights past 2wd is this what im lookin for or should i contn searching
