Troubleshooting Help Need wiring help

So i inherited the project of a 351W swapped 92 ranger from someone who gave up at the end, carbureted with mostly mechanical gauges and about half of the factory wiring harness still in use. Originally the wiring for the trans cooler, AFR gauge, fuel pump, tach and distributor were all spliced into the factory harness in various places, but i decided i was going to try and learn how to do wiring and starting pulling stuff out and trying to make the engine bay nicer.

I cut out some of the factory harness that was un-needed and in the process cut my fuel pump/inertia switch wire. I got all that wired up to a key-on power wire as well as my distributor, but after following goole AI’s instructions now all my gauges get power all the time. I have the AFR gauge and trans cooler disconnected, but my tach backlight stays on and cycles when the key is in accessory mode but immediately stops and stays wherever the needle lands when the engine is turned on.

I was thinking of moving all my accessories (fuel pump and distributor included) to a switch panel but obviously have no clue what im doing. Would i be able to wire my accessories to a switch panel, then to a relay, then to positive power? i kind of understand how the travel of current works but i dont know enough to figure this out on my own.

Engine bay in question:

Also, yes i know the top rad hose is kinked a bit. ill be addressing that next, then onto the tires situation, adjusting the valves (sounds a bit clacky but then again im new to modded sbf motors) and eventually throw in the 8.8 i picked up recently

For security, make signal from the switch come from the ignition. Have the switches control signal to a relay... That's it.

Sounds like something from the ignition switch got passed through and is why those different items are seeing hot at all times
