How to take power from the relay carrier
 

I've searched for more information on this topic, but I think I'm missing some basic information. I have a 2000 base Boxster and I'm planning to install a Homelink device using these instructions that I found on Renntech:

Some of the instructions are also in this post: http://www.renntech.org/forums/index.php?showtopic=23307 because the author was installing foot well lighting and the Homelink at the same time.

I have assembled and tested the device, but before I start taking apart the car to install it, I need to make sure I understand how to tap into the power at the relay carrier above the driver's foot well.

I connected my power for the Homelink and the dimmer switch to (2) -- 999.650.320.22 -- connectors. The are for contacting the bridge/bridge plug in the relay carrier.

Based on some other posts, it seems like I am going to have to loosen the relay carrier to do this. Can anyone provide instructions or links to other posts that show how this is done? I need step-by-step basic instructions if possible.

Thanks
