The two "harnesses" involved are the fuel pump and the resistor in the engine bay. For the fuel pump pull the hatch Harper up and your will see the wiring. Just follor it 12inches up and you will find the 4 pin plug. The one in the engine bay is behind the RF headlight where the stock airbox usually sits

Just don't snip the wires so close to the plug you can't wire it up stock again if you need to.

Ok, one last question (I hope). If I am reusing the stock relay, which wires (colors if possible) do I connect? I can't find a good breakdown of the wires in my Haynes manual.
It has 6 wires, 2 connectors.
4-pin connector: fat blue, small blue, fat black/yellow, small black.
2-pin connector: small black/yellow, small white/black.

I got everything wired up today. It starts and idles like normal, but throttle response has improved, there's no more hesitation when I blip the throttle, and it doesn't act like it wants to die when taking off anymore. I didn't notice the 3800 rpm stumble anymore, either.
One thing I did notice, though, is that the relay I added got very hot to the touch. Not hot enough to burn my hand, but not far off. Is this normal?

There is a 10 gauge wire with a 30 amp fuse coming off of the battery (put there by the previous owner) that powers the stereo. I teed a 12 gauge wire off of that 10 gauge wire and ran it back to that relay. The relay only powers the fuel pump, the fuse is for both. The rest of the wiring is exactly as shown in the diagram.

I have a saying at work "Never trust anyones connections or terminations".
With that said, a 30 amp relay on a 30 amp fuse that isn't blown should not be getting hot. If it was pulling that much current, your 30 amp fuse would pop, so something else is wrong here.

After looking everything over again, I think the fuse holder is bad. I unplugged the fuse instead of disconnecting the battery to test all of my connections and I was still getting voltage at the pump. I'm going to replace the fuse holder and test everything again.
See, this is why you never trust anyone else's termination or connections.
