Here is the stock thermal linear actuator (arrow) next to the new Posi-Lok pushrod, dust boot, and adapter housing. You simply unplug the thermal linear actuator, tuck the other side of the harness away in the wire loom, and unscrew it from the differential using a big box wrench or adjustable wrench. The Posi-Lok assembly fits directly in its place. Add some grease onto the pushrod and some RTV sealant to the housing threads, and you should be good to go.
