Thanks, Klaus. Yes, I did quite a bit of labeling.

I only discussed the 12v plugs I added. I actually didn't add directly into the bundle that goes along the base of the windshield. They are in a separate bundle housed in a flex tube with heat shrinked ends taped along the original loom. So it's armored for future chafing. There several extra wires (that go nowhere for now) for any future needs. There are two 14 gauge power wires from existing unused fused circuits in the fuse box. One switched and one unswitched. They split and each fill two of four fuse positions on an auxiliary fuse block on the right side, which is labeled. It just sits on top of the rear inside portion of the kick panel. I'm only using two of the four fused positions so far.

One is a switched source to turn on an active audio crossover in the glove box. One unswitched source is used to power 5 green LED's with a tiny rocker switch in the 'roof' of the map pocket so I can see any items in the pocket at night if I need to. With the resistors I put on, they are pretty dim. The green color was to approximate the stock dash lighting. They are a bit too green so I may try sanding them to give them more diffusion and to possibly mute their color a bit. I think I put a 1 amp fuse on each of these circuits on the aux fuse block, plus the block is fed from an already fused circuit, so everything pretty darned safe. This way I have some extra positions for anything else I might want to add on the passenger side in the future.

I put a 10 gauge wire on a small, multi-mount ground block routed to one of the stock bolt locations where the steering support bar would be mounted low on the right A-pillar if it were a right hand drive car. That is a good solid ground there. So there are plenty of ground locations for these circuits ready as well.

What might go there? Well, I've been trying out a Chinese Yatour 'digital music changer'. It emulates a six disc changer, using the stock radio input and controls, I use it with an SD card but it can use a USB stick and adds an 3.5mm aux input. So you can play an ipod through it as well. It is a bit finicky on file naming relating to playback order and things like that. But as long as you read enough to know what it wants, and change file names accordingly, it works pretty slick. I'm liking it quite a lot. I was also thinking of adding Sat radio in the future when we can afford it again. So there's that, too.
