Start conversion process by securing the supplied IPCW sockets to factory tail light wiring harness with vehicle's MIDDLE socket first. The middle black socket on the vehicle contains 2 black wires, 2 brown wires, and 1 yellow wire with a black tracer on it is what we are working on first. Take the supplied IPCW socket BLACK wire and secure the red connector around the BLACK wire on vehicle's middle socket harness.  Clamp this connector tight to secure it properly. Next, take the supplied IPCW socket BLUE wire and secure the red connector around the BROWN wire on the vehicle's middle socket harness.

Now the last step for this middle vehicle's socket is to remove the light bulb.  (You will not re-use this bulb in your IPCW LED tail light.)

The very bottom socket that is for the reverse light still has the factory bulb installed will be the first one that you secure into the back of the IPCW tail light. The next socket to install will be the middle converted IPCW socket into the IPCW tail light.  (IMPORTANT:  The plug in the IPCW light must be installed into the socket matching the black wire to black wire.) Gently twisting the socket to make sure it is secured properly. We now will install the small gray socket into the back of the IPCW tail light.  (This socket is not used so there will be no electrical connector to plug in.)

Now align the two securing tabs of the IPCW tail light with the body plugs and install the light onto the vehicle.  (This may require slight presure to fully insert the locating tabs into the body plugs.)
