okay so the hook up for the speedometer is on top of the dif case, above the driveshaft, but why wouldnt the rear end have abs i know it is from before 93. Does the rear end have to do with abs? i thought the brakes only did. Also how do i find out if this rear end will work with my front, i hear that you will tear up ur transfer case if the rear end isnt in sync with the front end? im nopt to sure i just dont wanna fuck up my shit when i put it in 4x4. i havnt yet just in case. And yes the od light im worried about that it starts to blink when i guess it kicks in to overdrive, because if im at idle it doesnt blink when i start it, but when i get going it dont stop
