Good.
Have you worked out the current draw to determine that you 'needed' a 30A fuse, or was that just waht you had ?
Anyway, ignoring all that ...
To make the lamp illuminate (in my drawing) you put the relays coil to ground (with the switch) which energises it and the battery power is fed from 30 to 87.
As you want the lamp to light when another one does then you would put 12V (from the other lamp) to 86 on the relay (in my diagram) in place of the thin red wire...
Does this help ?
In this pic the Dash Mounted Light Switch is substituted by the 12V from the High beam ...
