Not Knowing the brand or having a schematic....beats me. I opened up a Sony head unit once, and promptly closed it back up. Hell inside those things.

If you can find a left or right analog signal in that loom you still may have signal level issues. You might want to think about hooking wires directly to the pre-amp circuitry instead. I've done this on larger scale amplifiers, but there was additional signal switching circuitry involved.

I'd probably just get a new head unit though, chances of frying this one at some point are rather high. I can understand the whole "wanting to keep it stock", but these ease of swapping out with a newer "stock" unit, or a nice after market just can't be beat.
