You don't really need a link. The procedure is pretty obvious:

1. Pop the rubber dust cap off the back of the lamp housing. (Low beams are on the outside).
2. Disconnect the wiring harness from the lamp by grabbing the connector and pulling straight back.
3. Un-latch the bulb retainer clip. (use a small mirror to look in the housing to see how it works if you can't figure it out by feel).
4. Remove the bulb.

Reverse the procedure to install the new bulb.
