Not a wizard but here's mine two cents...
A relay is used to provide power at a "standard" rate without
the normal loss in voltage due traveling through the wires...
As far as Ron was asking, the relays are in the "power center"
under the hood and should not be "connected" to the computer. I think
that someone had the idea that a relay is a fuse, it is not. However,
if you screw it up really bad you could affect the computer through a
electrical spike like when jump starting your truck incorrectly....
