So unless your running 8-9 transformers a relay is OVERKILL.

You can run 1 wire (The switched Ground wire from the dome light) to the ground of the transformer directly, Then use a Constant Hot from the fuse block under the dash. That's how I did mine when I had my focus, then I wanted the Ability to leave them on all the time so I put switches in later.

Hope this helps !

Troy.
id like to see how this isnt false, but im not having any luck...

there is no switched ground wire in the dome light circuits. period.

there is a constant hot, a constant negative (switched AT the light) and a fader negative.
