[QUOTE="Sierra Nate, post: 8722350, member: 673019"] I think the reason you hear about the short ground wire rule is more related to the fact that there is always a good location for a ground within 18 inches of where you need it. Wire will inherently have resistance. The bigger the wire the less resistance per foot of wire. Shorter lengths have less resistance than longer. If you go Longe then you also need to go bigger in order to keep resistance equal. Your not going to get a bigger ground wire than your frame in most cases. Even a unibody has less resistance than a 30 foot long piece of 0 awg wire. Properly grounded to the chassis is always going to be the best ground...unless you can run a short 0 wag to the negative post. If your ground is over 18 inches then grounding to the chassis is probably better. All that said...there are plenty of ways to run a proper ground more that 18 inches. [/QUOTE]
