Power tap, 12v always on, 12v ignition, ground Where are you guys getting your 12v constant & ignition from under the dash. I don't want to wire into the fuse holder, I'm sure there is a way to wire into the harness somewhere under the dash ? I'm trying to tap out a location for a stand-alone fuse holder that will be in the interior so I can just add my accessories to the stand-alone fuse block as needed. I would also like to know if there is a particular place to get a good ground in the interior of the car ?

If you're going to add your own distribution block then I recommend using the three power outlets in the fuse panel that are designed for that purpose. Otherwise, you could be overloading an existing circuit when you add accessories later. BTW, brown wires are usually for the parking/running light circuits so always test before selecting a wire to tap.
In the fuse panel on the end of the dash you will find three single post ports (not double post like an ordinary fuse port). They are labeled BATT (constant power), IGN (ignition controlled power) and ACCY (same as ignition but also stays on during RAP operation like the radio). Remove the bolt holding the fuse panel in place so you can swivel it away to run wires from behind, then run your three source wires with spade terminals around the side and plug them into the ports. Replace the fuse panel and run the wires to a convenient location such as under the dash behind the console. These ports are 15 -amp circuits that GM put in specifically for adding aftermarket accessories.

Wow, great info guys. I just looked at the slots on the fuse panel this weekend and I was wondering if that was what GM intended. 
I will definitely be using the fuse panel now. It will make for a much cleaner install. Thanks for the extra input on the subject.
