Chris,
I considered welding wire but I already had a 20 foot chunk of new red 1ga Taylor wire so all I needed was a chunk of black. My never used buzz box almost sacrificed its' leads for the 'cause' but it is 4ga.

So far my American Autowire 'kit' has been close to pain free - it's just the starter and ground cables that haven't been.

Do you recall when Boyd's show was on - and on the list of work was "wire the car this afternoon"? No way did they custom wire a car in an afternoon - even with several guys working on it. I always got a chuckle out of that after doing a couple of cars previously. My dash, which is off of the car took 2 days to sort out!!
