Default Relay Help

So I got some PIAA lights once again and their fog and use 85w I was told I would need a standard 40 amp relay and an inline fuse or fuse?

Does anyone have a link to the 40 amp relay I could buy online and the inline fuse or fuse they are talking about?

You can get a standard 40 amp relay and an inline fuse from just about any auto parts store. I think Wal-Mart may have them too, in the automotive section.
Here is a wire diagram for the relay.

X's 2. Except I would be careful about buying cheapos from some discount stores or you could end up with an annoying buzz.

If there 85w each that's only a 14 amp draw, and if you supply power to the relay from the batt. It won't buzz .

Matt, I'm pretty sure you want a single pull single throw (SPST) or single pull double throw (SPDT) relay. Your pick looks like a SPDT to me, which is fine, but make sure to double check the specs.

Sorry I don't understand? Do you have a picture or link? Some guy at one of the Car Meets gave me a relay that worked for my lights for a little bit but then it blew out. Haha the same guy gave me another relay but that one also blew out as well.

It says its good for KC lights and up to a system of 4 lights what is the difference between a single pull and a double throw?

And what are these inline fuses everyone keeps telling me about where are these located would I have to replace a wire in the wiring harness to install it?
