Default 1966 wiring harness

Well after fighting light and dash issues I am going to replace the fuse block and dash harness. Who makes the best most original type harness for the 66? Don't want a cheap POS and have seen reviews all over the place from all companies.
Thanks in advance.

My 66 was a basket case when I first got her. Some idiot tried splicing in a Painless wiring harness for a 68. I was able to find all original online and it works perfectly and is easy to follow in the shop manual. Just had to get a fine brass brush on a dremel to clean inside the fuse contacts. I spent less than what I sold the painless kit that I removed.

Another for M&H. If you have any modifications they can make a harness to fit.

I had American Auto Wire make a replacement GM dash & engine compartment harness for my convertible. Everything fit perfectly. Plug-in and go!!
