Does anyone know off the top of their heads if a 2021 Classic would have + or 0V switched headlights?

I just want to fit a temporary front number plate LED light bar, one of these sorts of things:


Will only be a temporary fit until I sort out some projector headlamps.

WIll drive it via small relay, just want to know if the factory high beams are +12 or 0V switched so I can connect the right side of the relay coil to ? My Toyota has 12V to the high beams all the time and the 0V is switched. From what I can make out off a few diagrams online it looks like the Ram might be +12V volt switched headlamps.

I did something similar on my 2016, connected to the positive wire. There are only 3 wires in the headlight harness per side, a shared ground and 2 positives.

Just to give you another option instead of tapping into the factory harness , I got one of these harnesses below that comes with a remote FOB, relay, fuse, switch, ect. for less than $20. This allowed me to wire up an auxiliary fuel pump without running any wires into the cab and a simple 2 wire hook up to the battery or a key on only wire under the TIPM.
