LED Headlights w/ harness upgrade?

Back before the LED headlight craze, I upgraded put an ARB headlight harness in along with some bright ass PIAA bulbs.

Can I swap in a pair of LED headlights with the upgraded harness installed? Do I need to run the stock harness? Or does it not make a difference?

You should be able to just install the new LED headlights and plug them in , all the upgrade harness does is give the headlights full system voltage for brighter lights .

That's my assumption too. But wanted to make sure I wasn't missing anything.
