Sound deadening no worse than an E46. Basically a group of wires that run along the sides of the car front to rear, but there are definitely more of them. Wrap them in a nice conduit and it should clean up nice (but don't use the cheap split loom crap that everyone uses...that looks horrible).

Pics from my interior stripping and paint. I did eliminate about 50lbs of wiring and modules because it's a race car and there was plenty that I didn't need which cleans up the wiring a lot more.
