12v dc 3 way switch

Can I use The 202U to trigger relays for my LED light bar? The light bar has 2 relays and a 3 way switch. What is the best way to wire this? I’ve got 12v dc wires run for the 202U in the vehicle already.

Can you send the led light bar’s manual with schematics? thanks.

Both relays are identical

I think the problem can be divided into two steps.
Please see attached photo, thanks.

Are the commons jumped together in your drawing?

Yes, so the white neutral wire is either connected to blue, or red, or disconnected.

In this way, our receiver replaced your 3 way switch.
