The relay sent with all the install kits being sold on
ebay, will not work because they are an "inline" style relay.
What you need is a factory, "plugin" style.
It will run you about $50 believe it or not.
(Car parts are so over priced.)
All the extra parts included with the Factory style fogs available on
ebay are useless.
The kits were made up for cars that don't come with a factory wiring harness already installed.
So if you can purchase just the lamp assemblies all by themselves for less money, then do it.
