If you want to rewire the car with aftermarket kits, I used a Centech panel in the bird. I bought the separate wiring harnesses with the wires marked every few inches. I also used the fan controller.The wires terminate under fine threaded screws, and it’s worked fine with no problems for 15+ years.
I’ve also used 3 Autowire kits and they are first rate. Lots of extra connectors, and great instructions.
At least on my bird there’s also a couple circuit breaker under the dash. One’s for the power seat, but I don’t remember what the other one protected.
If you want to stay with the stock harness or add just some addition circuits, use a small panel for those. They’re kind of old tech, but fusible links are still available to use where you tap off the battery, gen, alternator. Keeps from burning the works down, and cheaper than maxi fuses.https://www.centechwire.com/Fuse-Panels_c3.htm
