You somehow allready tapped into you dome light and ran it to a swithch/light and ground. Tell the parts guy what you are up to and he will pick out a relay for you. Once you get it they usually have a wiring diagram etched into it. If you have a 12V supply or battery laying around an Ohm meter and small jumper wires which you can grab at Radio Shack. Than you can play around with it and understand how it works. Kind of a fun project. The side of the relay that is normaly closed will go directly to dome light source you found. The other input will go to the switch you installed and than to 12V source like the battery. Just using battery for an example I would try and find a 12V source that works off the igniton in case you would forget to turn the LED lights off thus draining you battery. Output on the relay goes to LED which goes to ground. Good luck and have fun.
