I'd like to wire my bed lights to come on with my dome lights and to be able to manually turn them on by a switch. Can anyone confirm if I have this correct:

30 to 12v
85 to ground
86 to dome light
87 to lights
87a to switch

Do I need a diode, and if so where?

Also, if I get an illuminated switch will it be constantly drawing power?

Thanks for any help!

After doing more research I found there is a better way to wire this
