I was installing my Viper 5901 and I'm seriously not in the mood to relocate wires into my engine bay. I'm trying to keep my install as stealthy as possible. So where would the hood pin in wire be inside the dashboard area?

Also, I want to locate the keysense wire, and tachometer sense wires. According to the12volt.com I can use any ignition wires I want, but I was told on my350z to use a fuel injector wire to get the most accurate reading?
