Installing an American Autowire Classic update wiring harness

I went through the items you suggested and purchased them all, except for the wire strippers. I have an old version that works great. I was on the fence about the AA crimping tools, but pulled the trigger after reading similar thoughts on multiple threads. I’d rather pay up front for something that is proven effective. At this point, I’m so far in with the harness and all the other aspects needed, that not paying the extra few bucks for the exact tool needed to perform the job at hand that I’m already $1500 in to seems like a bad idea. I’ve already failed really hard at doing it “my” way/the cheap wrong way that I don’t care about saving money when it’s only a couple percent on top of the pile. Thank you again!
