Default Factory headlight wire colors?

I picked up a set of auxiliary street legal lights that I'm going to trigger using relays from my 2017 factory LED headlights.
I need to find the factory wire colors for the following functions of the factory LED headlights, can someone help me out?

1. low beam
2. high beam
3. parking lamps
4. turn signals (left and right, if they use different colored wires

Thank you in advance.

Default Does this work for a 2018 f150 with LED headlights?

They mention the drl (daytime running lights) but don’t tell me which color wire is for the drl. Also is that the best wire to connect them to? When will the lights be on exactly? Just the daytime? Will they be on at night? Are the drl lights the same as the parking lights or the amber colored turn signal lights? When I turn my turn signal on will the raptor style light flash along with my turn signals?

Sorry there’s a lot here, basically I have maybe 5 minutes worth of work left if I just knew the damn color of the wire I’m supposed to tap these into on a 2018 with LED headlights.

If you only want them on with the parking lights, then use that wire.

My drl lights are on all the time, day and night on the 2018 f150 with stock LED lights. I’m fine tapping into those lights but I don’t know which wire is for the drl’s. I found a wire diagram for the 2017 f150 with stock LED lights, do you think that diagram would be the same for the 2018?

Can you share the diagram for the 2017? I have a 2016 and want to add a grill light into mine. I’m also trying to locate which wiring harness to tap into.

Did you ever figure this out? I’m running into the same problem wiring up this new raptor style grille.

By the headlight wiring harness it’s the gray wire with the blue marker. That’s the running lights.

That's for the 2018 diagram right? I only ask cause I know it’s different, and I haven’t been able to find it anywhere. Or am I mistaken and it’s the same? What color is the negative? Thanks for the quick response.
