What you need:

Tools:
10mm socket
Flat and Phillips head screw drivers
Soldiering Iron
Wire stripper/cutter

Materials:
14 or 16 gauge wire ( i used speaker wire as it is really two wires making it easier to fish around your interior)
Solder and shrink wrap tubing (best method)
or at the least
Crimp connectors and electrical tape (ok method)
Toggle switch
Double sided tape to stick the switch somewhere hidden

--1)V

Locate your car. Hopefully it is where you left it the night before. After this mod you can sleep easier.

--2)V
Locate and remove interior panels by passenger side right foot well. (s13 pictured, S14 may differ slightly)

--3)V
Locate ecm and remove the 10mm bolts holding it to the chassis. Remove harness from ecm with the 10mm bolt and refer to diagrams to find fuel pump relay wire.

--4)V
In most cases the fuel pump relay wire is b/p or black with a purple stripe. Cut the wire about 6 inches from the ecm. Then connect the two 14 or 16 gauge wires one to each end of the cut fuel pump relay wire.

--5)V
Now run this wire under the dashboard to the driver side foot well. Connect your toggle switch to the two wires. Hide the switch in a creative spot. Start the car with the switch on. It should start and idle normal. Flip the switch off and the idle should start to bog down as the engine starves of fuel. If your switch works correctly your done! Bolt you ecm back in and fasten all the interior panels back together. Hide the wires as best you can and Job complete.

here you go. red top pinout is 104 color is b/p

You lose. Again this is THE BEST way of doing it. It doesn't mess with the stock power circuit of the fuel pump. It only controls the relay which controls the circuit.

not bad dood, I pulled my article, yours is much better.

Thank you Thank you

GREAT write up by the way man, love it

If you turn your car off then flip the switch to kill the pump. Then come back and flip the pump switch so the pump will turn on before you put the key in, then turn on the car it should have no effect on starting. If you put your key in turn it to on then flip the switch it wont prime the fuel system and give you a longer start. The pump runs for about 3-5 seconds after you turn the key to the on position so if you still have the pump killed it wont prime.

Correct but you should flip the switch after the engine has completely stopped spinning, and flip the pump back on before even putting the key in to have a seamless and closest to stock functionality.

If you think thats bad you should see my engine mounts. They have this stuff for sealing windshields on them. But seriously i have had it like this for months now without any problems. The duct tape seems to be holding fine too.

KA-T why settle for anything less?

thats nothing, my motor mounts are hockey pucks right now.

but im there really is no risk of fire from them. or even just arching out and burning up the ecu.

No risk at all. That wire carries like .5 volts if that to the fuel pump relay. Remember a relay really doesn't need that many volts to be pulled in. Also there is really no issue with using duct tape either.

Is the terminal layout the same for a s13 blacktop and redtop?

plus i'm getting a little confused from step 4

4)V
In most cases the fuel pump relay wire is b/p or black with a purple stripe. Cut the wire about 6 inches from the ecm. Then connected two wires one to each end of the fuel pump relay wire.

- so the fuel pump relay wire we cut - then we solder the toggle switch inbetween the cut wire...?

YOU ARE THE ****ING MAN!!!!!!!!! quote that ****.

No need to ground anything. Just put a switch on the fuel pump relay wire and go!

The best thing to do is follow the sr diagram and check if the wire is black with purple strip. Which I'm sure you will find to be the case.

Correct!

Also I reworded step 4 to be a little more clear. Along with the picture there should be no issue.
