I am trying to wire some switches through a relay to an led bar. I have a relay box unit with 6 relays for 6 items that I plan to use.

The wiring is as follows, we’ll use #1 as my example.
I see that the large white is the power for the light, and thin white power to switch. I will ground the light at itself, leaving me with a power wire from the light which would go to the switch. What I need to understand, is how to connect the light to the switch, and the switch to the relays.

I am trying to fix a problem created by a previous owner and can’t understand this. They never had a relay so I decided to add a pre wired one. I am looking to wire the switch to the relay so the light is on when the accessory is on like the second photo diagram. The relay kit comes with the trigger wire and accessory wire together for each switch. Can someone explain how to hook the 4 prong switch up correctly?
