I'm not sure how much wire the Spartans come with. The aux plug for the MS3 comes with about 6" of wire. Pay attention to which way the plug housing is facing when you insert the pins. That one bit me in the ass last time.
You'll need to run wires for the flex fuel sensor as well. It all depends on where you mount it. My wideband modules are under the steering column so I had to run wires from the passenger kick panel to that spot. As well as run wires from the flex fuel sensor in the wheel well to the ECU.
You could probably get everything hooked up in a weekend. I spread mine out over a couple weeks. I need to pull the ECU to change the ground for the flex fuel sensor, but I'm being lazy and dealing with trying to buy a house.
