ok, I am enclosing a picture of the relay that i have and i just wanted to make sure that i am gonna wire it correctly....first of all i dont have a harness so i was just gonna sauter the wires directly to the terminals, hopefully that will be ok? the fuse holder off of the positive terminal of the battery will connect to #30, the new bigger 10 gauge power wire will connect to #87, the old fuel pump power wire will connect to #85, and i will have a ground wire connected to #86....i am hoping this is all correct as i am about to do it all now :)

Thanks
Chris

Just understand that if your car crashes and burns to the ground because you disabled the ECU's ability to turn off the fuel pump when the engine stops your insurance is void because of your mod.

The stock system works, if your having problems with hot starts try fixing that problem not hack up the pump wiring.
