89 K5 with electric rear window. Mine finally bit the dust. I can use the switch inside the cab but the key switch on the tailgate is no more. I tore into over the weekend and found out that the electrical connection that plugs into the end of the lock switch is busted. Does anyone have or know where I can get this wiring harness and a new switch. I called LMC and they only have the key switch. Any help is greatly appreciated..
