check under the bed along side the gastank between it and the driveshaft i beleive there is a cable that goes into a weird junction and two cables split off to the axle after that but there is a tightening nut in the middle it should be fairly obvious. i would say if you don't care bout it working later just snip it or try to loosen it up with some wrenches if you can idk ill try to draw a picture of what it looks like.
somethin like this
