OK... I just completed my first ever car mod. Thanks for the holding my hand through it BeetleBailey!

For the most part everything went very smooth. The problem I encountered (becuase I'm a total novice) was not knowing how to attach the 12V wire to the main wire harness. My kit did not come with a T-splice so after a little Googleing I found a site that described how to solder a splice. That's what I ended up doing and it worked great.

Funny story... I just got the car a few weeks a go so I'm still learning how things work. I got everything hooked up and working in about 3 hours (it took me awhile becuase I'm a total novice). I was happy and I went driving around and things were great. The next morning I drove my car down the street and a load beep went off and a warning light came on. I was totally freaked out. The first thing that popped in my head was "what did I do!?" I thought for sure I screwed up my car somehow during the install. I checked the manual for the explanation of the light... and in my haste I mistook the tire-pressure light for the brake warning lamp (yeah... I know... dumb move). Anyway... I spent the rest of the afternoon trying to figure out how my wiring job had shorted out the brake system...
BeetleBailey was very gracious in helping me troubleshoot. Then, just when I had lost all hope and resolved to take the car to the stealership... I discovered that it wasn't the brake light that was on... it was the low tire pressure light... and sure enough the rear diver side tire was low on air.

So moral of the story: RTFM (more carefully).
