Also the harness from ez has a black wire splices from the (red) ignition switch power, not sure what this is.

The brown/white wire from the ignition switch is usually wired on the same terminal as the 12 gauge brown accessory wire. It is a small gauge wire and it is a resistance wire which runs from the key switch to the inside of the firewall block where it joins with the 16 gauge brown solid wire on the engine side of the block and runs to the external voltage regulator. If you or someone has converted the alternator to an internally regulated SI or CS then this is the wire that feeds the excitation terminal on the internally regulated alternator. It may be splice to the white wire in the EVR plug and run to terminal one on the alternator, or it may go straight to the alternator and have a resistor in-line connected to the L terminal on a CS style alternator.
This is how the key is wired. The black arrow to the left is the brown wire to accessory and the wire just below it is brown/white stripe wire. I do not know of a black wire spliced in with the red power wire. Black is usually designated as a ground wire and it certainly wouldn't be connected with a red power wire.
Here is the cluster connector for the gauge dash. it shows the stock wire colors and tells what terminal they go to and where they come from.
They may be different from the EZ harness you have.
