Hey Guys,

  I feel like i'm asking the same questions over again..but i'm still in the dark here...heres where I am..i have a fuel pump relay switch that has a wire that needs a key on 12 volt power..I have a becool radiator with twin fans..it has an ignition key on wire..exhaust dumps with a key on power wire..and an msd ignition bow..with the red wire for key on 12 volt source..i ran all these wires to the glove box..can i spade connect these into the fuses for key on power?  thanks!

Hey, Emanscharger

I guess you didn't understand the answer I said in your other post Key'd ignition, you don't have to run any wires back to the fuse panel, you can run just one wire that has power to it when the ignition is switched to multiple relays, one wire or switch can switch on as many items as you like, look at the first link in the other post you had it's a fuse panel from advance auto that has six positions you can run six items off of the panel, you only need to run one wire that has switched power to the number 86 terminals of the all of the relays terminal 85 is the ground, terminal 30 is contant power from the battery  and terminal 87 powers what ever the relay is for fuel pump, fans etc.

Note there's a few ways to wire relays up the above example if just one way, you can wire it different ways other than whats above.

You need to run a heavy gauge wire for the fuel pump because it is is usually in the rear of the car maybe a 12 or 10 gauge wire and a forty amp relay just buy the relay sockets they sell on parts express for the relays there colored wires you can figure it out if you read the the examples I put links to in your post http://www.partsexpress.com/resources/relays.html use the example of connecting an amplifier except you have fans and fuel pumps, the relay doesn't care what the item is as long as it doesn't exceed the amperage of the relay.
