Opinion on universal wiring harness

I have one from Speedway Motors for my rat truck. It's a 21 circuit, which is WAY overkill, but I got it on one of their garage sales for 89 bucks with free shipping. It's fantastic quality and each wire is individually marked. Even came with GM style headlight switch, dimmer switch and a cool universal old school turn signal switch. As long as you have the ability to splice, terminate ends and so on, don't be afraid of it.
