Did the electrical install today. I'm using the stock amp and speakers, so I got these two adapters:

Pretty straightforward, just connect the wires based on their descriptions (not necessarily colors!). One thing that threw me is that there is no ground on the power harness. My first test revealed that the black wire on the smaller "clock harness" is not in fact ground, as I had expected. So I attached the ground cable to the screw on the radio mounting bracket, and it appears to work fine; no ground noise. I'm not sure where the stock radio gets ground from, maybe the antenna or amp connectors.

So it's all in and good. Pictures tomorrow when it's light out.
