Ok when you reference a product that someone else hasn't mentioned, you should make it clear that you're talking about some other brand. That said, those cactus look to be really cheap triggers, I'm not saying they aren't good, I'm just not familiar with a lot of the lower brand names, I only use pocket wizard brand which is top of the line.

You attach the bottom of the L to the bottom of the camera where the tripod attachment hole is, and then your trigger on top with the PC x-sync cable.
These statements are not meant to sound angry, I'm just often direct, so please don't read this the wrong way, you're doing fine, obviously new, very anxious (I probably sound like this to a lot of people here) but try and google some of this stuff before you ask, in fact, try and learn more about this stuff before you buy an expensive camera that you're not sure how to use HAHA And READ YOUR RB67 MANUAL!! If you had you wouldn't have asked about the x-sync or other questions.
