I'm putting in the 3G as you probably have guessed and going by diagrams I've seen I'm going to be running 4 AWG wire to a 175 A fuse and then 4 AWG wire to the starter solenoid. I'm getting some free 4 AWG cable from a stereo shop and am going to meet someone who can cut and crimp it properly. I want to do this this week and won't be able to get to my car until at least this weekend so I was wondering generally how long I should cut the cables to get them crimped? Also where do you guys mount your fuse? Fender?
