Hi all, this is my first post so please forgive me for sounding too newbie like. Today I was able to buy a 2005 Z4 3.0 (51k miles) for only $500. Of course seeing as how it was only $500 there was definitely a going to be a few issues with it, but honestly nothing major...I think. The car has been sitting untouched for a few years so I didn't even attempt to start it because I want to drain and replace the fluids and gas first. The main issue that I've discovered is a rat or something crawled in the engine bay and chewed a bundle of wires coming from the passenger side firewall. I haven't tried starting the car, but everything seems to come on when I turn the key. Does anyone know a: what all is in this bundle and b: can it be easily replaced. Pics attached, thanks for your time.
