Sorry let me explain.

I have a 2004 ltd which doesnt have the no. 17 and 18 fuses that the later crossfires have.
What I have is a black box on the suspention turret just in front of the battery.
click the lid off this black box and you will find 3 large black wires bolted to 3 rather hefty fuses.
The middle wire is marked up as Hydraulic Unit(Traction) this is the one you need to cut and connect the toggle switch too.
before i did this i could make the wheels spin but the traction would kick in and bog down the motor even with the traction button pressed.
Now when I use my toggle switch i can spin the wheels right down the road!
The down side of this is that you also lose ABS BUT I WILL ONLY USE IT FOR LAUNCHING
