Having rewired more than a few projects over the years, I've had the opportunity to use harnesses from EZ Wire, Painless, QuickWire, and Rebel. All have had their pros and cons. All will work depending on your comfort level with wiring. I have a friend that ordered a Speedway 12 circuit harness for a project that was sold before completion and I took it off his hands for my project. The quality is very good, the price is very reasonable, but the instructions are written for an absolute novice which may be helpful to those that want to tackle rewiring, but are worried about getting in over their head. This is the link: https://www.speedwaymotors.com/12-Circuit-Mini-Fuse-Universal-Hot-Rod-Wiring-Harness-Kit,2352.html
If you scroll to the bottom of the listing, you'll find the instructions in a PDF. They are the best I've run across and are as close to plug-n-play as you are going to get.
I played around with several fuse block mounting locations, but in the end, the easiest place for mounting and access to the block was under the left side of the dash. The fresh air/vent plenum is constructed with a fairly wide flange. The flange provides a solid mounting and allows you to tuck the fuse block out of sight but easily accessible. I just fashioned a mounting plate out of 18ga. steel and drilled the mounting holes. Fast, easy, and functional. I'll have to provide the actual install photos later. I need to paint the interior before the harness gets installed.
