Could someone post up a wiring diagram (sketch, whatever) of how to hook up a second fuel pump relay so that it takes some of the load off of the primary relay. Everything is working on my car yet the other day it was hard to start and when I looked at...

You don't want that.
If you get into an accident where you break a fuel line, with the COR bypassed the fuel pump will just keep spraying fuel.
Be thinking of the Circuit Opening Relay.
The relay turns on, I even switched them around, I tested the pump outside and it works, but there is no power at the pump and the truck just cranks. If it matters it matters it does not have a ballast resistor.
