I do not have a video however when I installed mine I pulled the bulb unit out with a flathead screwdriver, there is a clip on each unit to remove it. Then I twisted the wiring/unit section by 90° and it comes out.
For the resistor pull out the unit, turn the bulb socket 90°, put the resistor in the socket, plug the LED into the resistor socket then put the resistor/bulb into the unit. It should look like
Car wiring --> resistor --> LED --> unit.
Hope this helps.
