It's better to put the relay off the fuel pump circuit (if you have an electric fuel pump.)
If the engine is turned off or the engine dies the power is cut off to the fuel pump.

I got it all wired up over the weekend and it worked great! I can't believe I didn't learn this earlier! I can think of so many electrical applications I've done in the past where this would've made things so much easier!
Give a man a match, and he’ll be warm for a minute, but set him on fire, and he’ll be warm for the rest of his life.

To peovent the glass jar from blowing up use a uased press blanket from a prant shop it will blow the top off befor it blows the glass apart.

I agree. The diagram needs a couple small corrections though.Originally Posted by Dewayne

The first 25 amp fuse should be between the relay and the battery. Also, there is no need for the second fuse because it's all in series.
There is also no need for the power switch.

My father called me last night and I helped him wire up his Suburban over the phone. It worked great for him as well. I really think this relay thing is the way to go!

To prevent wires from melting and posible fire install the fuse as close to the battery as posible.
I have updated my drawing, see above
