code 3 h2 covert siren wiring question

[ask80]

hi. I have a steady burn light wired to aux 1 and would like it to light up when 3 is pressed., along with the other lights that are wired to 3. how would i wire this up? it seems like splitting the power to both doesn't work as the aux 1 would light up all the lights wired to 3 instead of just the steady burn light by itself. thanks

You’ll have to use a relay

what kind of relay do you suggest? thanks

youll need some resistors as well to prevent back feeding...
