dan,

for the lead off the battery, there are battery terminals with all kinds of post options (side, top, etc.). here's a page for you:

for the switched, i always take it off the ignition harness.

go to www.the12volt.com and use the wire location search engine. it should tell you exactly what color the wire color is. that is one of my favorite sites for wiring questions.

but even more importantly, im excited that you are installing a frybrid kit! take a lot of pics and notes, i'm definitely interested in learning from your experience.
