wiring / what's the minimum?
Hello, I am knee deep in weeding out the harness on my 93 miata. I plan to run new wiring for lights & fans. I have eliminated power steering, ac, air bags, and hope to eliminate the stock dash in favor of a traqdash or standalone gauges (budget dependent). I will be running a MSPNP in order to eek a bit more out of my 1.6 & allow for easy engine upgrade path in the future.
What is the minimum I need to keep to allow the car to operate properly? do i need to keep the diagnostic box that sits in the driver side engine bay? does anyone have a diagram that illustrates what plug is interfacing with which fuse or relay on the passenger side of the car (specifically the fusebox on the passenger fender).
Thanks for any advice, It is much appreciated.

The factory wiring manual is great. The only problem with them I have is I wish the various connectors between the engine/front/rear/etc harnesses were done a little differently. I'd like to see the pin listed next to "X-9" or whatever connector. That would make life much quicker.

I started at the ECU plug, found every wire on a wiring diagram, and then decided whether I needed it or not. If I didn't need it, I cut it and traced it out to its termination points. Repeat ad nauseum until you know what every wire in the car does.

Wiring diagrams that show all the small different plugs between the ECU and whatever it is hooking to. For example on the 94 miata there is a bundle that goes from the ecu into 2 or 3 plugs under the dash right at the firewall. No factory diagram shows those connectors under the dash. Or the 6 wire plug for the injector harness, it is absent from the wiring diagrams. It just shows a straight wire from the ECU to the injector.

I'd Start with the auxiliaries and move in, not touching the ecu. Trace back connectors like the power windows, defrost, door lights, door buzzer, radio, cc, etc.
Unfortunately, you have the heaviest 1.6 wiring harness. 92s and 93s came wired for any and all accessories iirc. I'd leave the lighting alone, sans the light bar you wanna do.

I am eliminating the AFM, purchasing a MSPNP, and basically getting rid of most of the wiring that is on the drivers side.
I will need a solution for starting the car. also need to keep the brake light switch and fuel stuff. that is a pretty tiny bundle of wires.
i also ordered new gauges, all auto meter stuff. tach, oil pressure, water temp, voltage, fuel gauge. these will be mounted in a new metal center console along with the kill switch and fire pull.
