1968 GTX new engine wiring harness HELP

[hartdr75]

Looking for a bit of help on my engine wiring harness. I’ve got two connectors that I have no idea what they for. Everything else fits great though.

Purchased an engine harness from Classic Industries modified for ECU. You can see in the pictures there are these terminals that are not on the old harness. Any idea what they are for? 1968 GTX

Those are for the dual ballast resistor. Electronic ignition systems use the later style dual ballast resistors.

Thank you! I was twisting my head 360 trying to figure this out, just ordered one from my local parts store for $11.00!!
