Are you restoring or doing a hotrod? If just going with stock get one with as few circuit as possible but if you are adding a bunch of accessories like a big stereo, running lights, A/C, etc, you will want one with a lot more circuits. Outside of the restoration harnesses they are pretty much the same. Each wire is marked every few inches with where it is going. Spending a bunch of money might make you feel better but it’s not necessary. Good luck.
