OEM LED swap harness

So I recently acquired OEM LED headlights for my F250. I currently have LED bulbs in my halogen housings.
What harness is the recommended way to plug and play these lights?
The LED lights do not have a ballast, only 3 plugs

will my factory auto-on work as usual

and I do have Forscan, not very familiar with it but enough to get me in trouble.

i recently saw front and rear conversion harnesses on eBay Or I’m sure a search here will turn up a source.

Do a search (even though that function sucks here). Somewhere there's a big writeup on how to accomplish the swap and the parts that are needed.

You can also go to https://www.boostedgreygoosedesigns.net and he carries a bunch of custom built harnesses. I've ordered from him and the harness was just like a factory harness. For the money involved to buy crimpers, terminals, connectors, wires and then plan it all out, his prices are worth it. I bought the telematics control module harness from him and it worked like a charm. You can also email him via the site and he's usually pretty quick to respond. Tell him Griffalo from the F150 forum sent you.

Thank you I did see that post where he tapped into wiring and redid wires to adapt the plugs. I was more hoping to see what is the popular harness, plug & play.

Just installed an OEM LED headlight conversion harness from Black Flame Customs for a 2020. ‘17-‘19 harnesses are less costly.
Does require running a harness through the passenger firewall rubber plug and adding 5 pins to one of the 40-pin BCM connectors.
There are ~10 Forscan addresses to change. You will need the OEM LED drivers (ballasts).
FYI - instructions here: https://blackflamecustoms.com/wp-con...ht_Install.pdf
