Thanks for your email and patience waiting on a response here. I'm sorry to hear of the issues with your harness recently.

There is a diode installed from the high-beam to the low-beams that keeps the ballasts on when you select high-beam, so that was likely either burnt out or removed somehow.

If you prefer wire in a diode, it's a 1N5404 that goes with the stripe facing the low-beam wire coming from the relays
