Cerbo GX relay #2 current

Hi!
My Cerbo is fitted in a van, with some exterior lights. These lights are connected to 4 relays that control each of the sides of the van. With an internal screen, I can send 12V to activate the relays and light on the lights.

My question is if I can put a +12V to the common port on the #2 realy of the cerbo, and the connect the cerbo to the same internal screen, to activate the lights from the Cerbo. Will the Cerbo have a problem if the current from the other screen goes to his #2 realy? Do I need a diode or something in the middle?

Thanks!


Albert.

Sorry, I did not explained myself :(

I need the relay of the Cerbo to control another relay, but this relay is already being controled, so I'm not sure if the current will flow backwards to the Cerbo and broke something, or maybe I'm just thinking too much...

There is no current going into (the electronics of) the cerbo.
The relay is just a switch in parallel with the other switch.
