I am looking for a way to wire up a set of PJX bi-led projectors retrofit I completed for my 17 Ram Sport. I am having to run them off a relay harness as I did a quad build (2 projectors per side) and it is too much for the stock wiring. The low beams work fine, but the high beams are stumping me. The projectors require the low beam input to receive power for them to work (flip shutter). So I need a way to power both the low beam and high beam inputs at the same time via the factory high beam wire and have the low beam still work stand alone.
If I use a regular 4 pin NO relay, it works for the high beams, triggers both, but when the low beams are turned on, it backfeeds (proper term?) and turns on the high beams as well. I assume I need a diode here to prevent the cross feed to the high beam wires? Or so there a relay that has two outputs that are not connect when not powered and would allow the lows to get power and not send it over to the high beam wire?
Like this where 87 and 87b would be going to the high and lows beams when power is sent to the relay, but would not allow the high beam to cross feed when the low beam relay is activated and the high beam relay is not (as both relays would be wired together to the low beam input).

If that makes sense at all..?
