Charging system wire around 6 or 8ga

Well mine actually WORKS, so I am leaving it be until it doesn't. I've inspected the firewall connector and it looks fine. Course this car is all stock so there's "that".
Cool! So you installed wire bypass and ammeter still works? I am strongly considering doing this for peace of mind in my dart sport soon! So you just added this without modifying anything? If so I like this idea even more!!:)
