Ok so if I'm using a 5v relay the power for
the other side of the coil comes from the same 5v used to power the receiver ?

Thanks Bud I got it, I was under the impression that the coil would be energized immediately if I connected it to the 5 volt supply.
Thanks again, now I never have to worry about losing a remote.
