The blue wire that's at the relay goes straight to battery positive. Make sure to put a fuse inline.

So the blue wire from the relay would get solder to the blue power wire that runs to the battery correct?

The blue skinny wire off the relay gets soldered to the fat power wire the kit came with. The supplied power wire I got was red. Yours might be blue.

Thankyou for the reply! I’m finishing up the connections now just struggling with running the power wire from the pump to the battery

If you have ever ran a power wire for an audio amplifier it's the same concept. Hopefully it all works out for you.

Re-wire kit

What gold wire are you talking about? There is no gold wire wire on the kit.

Does anyone have the pictures from this write up?

Well since I couldnt find a how to on installing a rewire kit I figured I would write one. This is my first how to so hopefully its ok and clear enough. The kit Im installing is from STM. Found here http://www.streettunedmotorsports.co...rewire_kit.htm
The first thing you have to do is remove the rear seat bottom cushion. Pull on the 2 locks in the front of the cushion to release it. Then remove the black square cover on the drivers side. 4 phillips screws. You will then have to remove the fuel pump connector by squeezing it and pulling it off. Next cut the covering away from the wires. See picture

If you look at the wiring diagram it shows the thicker black and white wires are for the fuel pump

Cut these wires about 11/2" away from connector.

The relay connector comes with 5 wires

To be safe I removed the center red wire since it wont be used. It will come out by giving it a good yank on the red wire.

Take the ground wire the kit came with and put the gold terminal onto the end after stripping the wire. Slide the rubber part back onto the wire away from the end. I used some pliers to crimp the terminal onto the wire. You can either keep it this way or solder it. I highly recommend soldering all the connections.

Then after it cools off slid the rubber insulator back to cover the solder connection.

Do the same thing to the power wire. The shorter end from the fuse which will connect to the battery. Next you will have to find a good ground. I used the bolt which holds down the seat backrest. You will have to sand the paint away to get a good connection.

Attatch your ground wire

Next you will have to connect the relay to the vehicle wiring harness and to the fuel pump itself. Total of 4 wires. Connect the supplied red power wire from the battery to the blue wire of the relay. The yellow wire of the relay goes to the white wire of the fuel pump connector you cut earlier. The black wire of the relay goes to the white wire in the vehicle wiring harness that was cut earlier. The white wire of the relay goes to the black wire in the vehicle wiring harness. Next you will connect the supplied ground wire to the black wire you cut at the fuel pump connector. Here is a picture of all the wires connected

Solder all connections and tape them all. Tape the edge of the opening to prevent the wires from shorting out on the body as seen in picture. Tuck the wires in neatly and plug in your fuel pump.

All these wires need to come into the car along with the relay. To make sure the wires are not being smashed you will have to bend the cover plate to allow the wires to come through.

Tape the relay down as shown in the picture.

If you want put some of the corrugated tubing that came with the kit over the smaller wires

You will have to run your power wire up to your battery. Pull the fuse before attatching the power wire to the battery. Reinstall your seat and put your fuse in. Car should start right up. Depending on what kind of pump you have you may need and aftermarket fuel pressure regulator. I have a DW300 pump and its overrunning my stock regulator. Base pressure is about 43psi@idle. Mine jumped up to about 55psi@idle. This is with E85. Might jump up more on pump gas. Hopefully this helps some people out. If you have any questions or if I missed something just let me know.

I’m doubting my diagram I’ve drawn up from this is correct. The black wire from the relay (Pin #85) ((which is listed as a ground in stms description)) goes into the WHITE wire of the harness under the carpet? I can’t see the pictures from this write up. If anyone else can please reply to this with them.

So this picture is from SpoolinUp about how to rewire the fuel pump for a hobbs switch so you can maintain high voltage low voltage functioning of the fuel pump circuit.

You only tap the white wire on the fuel pump connector.
