Nice work rcurley! Not to mentioned an often overlooked step to upgrading an electrical system. Very clean wire assembly there with the nylon sleeving. Also great tip on the silicon and lock washers. Only extra thing I would have done would be to solder the connections during the wire assemble, but thats just the anal former wire rep side of me.
This is a great idea and demonstration by rcurley of the more expensive upgrade ground kits available from HKS or other companies being marketed from $80 to $140. Im sure rcurley's kit and self assemble costed much less than one of these kits, and allowed him extra flexibility in deciding how to route the cables for his particular application rather than a precut wire kit would have allowed him.
For anyone with the time to do this I highly reccomend it. Even without an aftermarket audio system this is definitely an upgrade. Companies that offer ground wire kits tout performance increases and better gas milage. Not only that, but how many of you have actually checked the condition of your stock ground cables?
As I mentioned before, this is one of the foundation steps to building a sound vehicle. Electrical upgrade 101. Upgrade all the weakest points and links in the electrical system, starting first with all easily accessible cables.
I gotta give you props on getting that alternator cable connected without taking off the entire alternator which is a pain. I think last time I upgraded I had to drop the suspension arms to get it out of there.
One question. How long approx did you make the ground cable from your alt?
