Strange ignition question

My plug was disintegrated as well as the new plug was the same shape but different size. I can't be only that "that" has happened to. Lol but I read the aftermarket parts did have an issue with wiring color as well as it wasn't installed into the plug, was in the box with the ignition
Ahh.

Well those are the two possiblities I can think of, assuming no seat belt interlock system. While that AFAIK was only for the starter motor it did have J3 connections.
To be clear, the two possibilites are:

1. The J3 is not getting power with key in start. It should be at the same voltage as the battery when the key is in start. If the battery is 12 V, then all of J3 should be 12 V. If the battery is at 9 Volts with key held in start, then J3 should be 9V. That's also enough to light a test lamp as long as the connections are half decent.

2. Distributor signal wires are backwards. They may trigger but the timing will be scattered or off.

Most likely J3 is not getting power in start. The connections from the ballast resistor to the coil positive and coil negative to the ECU are probably good since it does run.
