Indicator Light Switch

I Have 2001 5.2 4x4 Dodge Truck. I Am Having Problems With 4 Wheeling Dont Engaging. When I Put In 4l The Axles Is Spinning But It Is Not Locking In . So I Got Under The Truck An Was Doing A Visual To Look For Ne Damage Lines Or Hoses. . I Notice That The Indicator Light Switch Wires Wher Cut. It Must Been Done Before I Bought The Truck. I Am Trying To Trouble Shoot Wher They Go Too. So I Can Rewire Them . I Am Thnking They Run Up Thru The Front Of The Bumper Some How. I Dnt See An Other Wires That Might Have Connected To The Ones That Wher Cut. Does Ne One Have A Diagram That Shows Wher The Indicator Light Switch Goes Too.
