Headlight wiring harness

I have a heavy duty headlight wiring harness with two relays. When low beams activate they are on and when highs are on, the lows are also on. I would like to deactivate the feature because it would burn out the bulbs and the bulb also bubbles because both filaments ae lit up. Thanks

That's a new one. Most people want both on for some reason. What brand is this harness? Do you have a wiring diagram that came with it that you can scan? I have no reference to what you have, so I can't tell you what wire to move or cut.

it seems like the best solution would be to trace the wire back from the high beam activation spot on the relay, and jump that to the deactivation spot on the low beam relay, so that when current is supplied to the high beam relay, it cuts off the low beams
