Strange ignition question

As far as wiring, if there's no interlock wiring, then its pretty simple.
Look at the pentagon connector.
The two wires on the right of the pentagon connect with the distributor. They are not interchangable. That signal is amplified by the ECU and used to switch on/off current through the coil. That's the left pin (black w/ yellow wire originally) which must connect to the coil negative.

The pin at the top of the pentagon connects to power. Bottom left is to control the power on the original ECU's. That pin connects to the 5 ohm resistor. Red and green wire originally.
