heres some text off another forum..
This was on an 2002 so check the wire colors first, they should match up
"Get a 5k ohm linear potentiomer with integrated switch form MOUSER part # 31VM305 for $1.72 Also get 5 3M connectors part # 517-560 for 12 cents each.
Get one each of the following 1/4 watt (1/2 watt will do) resistors from either Mouser or radio shack: 2.7k, 3.3k, 3.9k, and 4.7k ohm. You will only use one of these, but you will have to pick the one you like best.
Take your "go" pedal out of the truck. It takes one or two screws and it unplugs.
Get some 16 or 18 gauge stranded wire to hook everything up.
Using the 3M tap connectors, parallel the switch on the pot to the red wire with yellow stripe and the red wire with green stripe. It doesn't matter which terminal on the switch goes to which wire. It's only a switch. By the way, this is called the TVS, throttle validation switch.
Now, using the 3M connectors again, tap into the grey wire with the white stripe and hook it to the center connector of the potentiomer.
With another 3M connector, hook the brown wire with a white stripe to one end of a resistor. Hook the other end of the resistor to the left side of the potentiomer, looking from the shaft side. This is called the TPS Throttle Position Sensor.
By the way, all of these connections are done ABOVE the "go" pedal connector, not on the pedal. I guess you could, but then you can never remove the pedal again.
Put the pedal back in. That's it.
Now here are the gotchas... I wired all of this up in the floorboard using alligator clips so I could try it out before I made it permanent. You may have to try several different values of resistor to get the idle speed up as high as you would like it. A smaller value will make it idle faster.
If you hook the resistor to the wrong side of the pot, when you switch it on, you will go into fast idle, and it will come down as you rotate the pot clockwise. You want it to switch onto low idle and increase as you turn it up, so you should be connected on the left side of the pot as you face the knob.
This control mounts nicely in a 1/4 inch hole on the blank panel just below and to the right of the steering column, just above the fuse panel door. Get a nice knob from mouser and it will look factory.
I hope this helps because I just can't explain it any more clearly.
Some one had also mentioned that you could take it to a dealer and tell them you would like it reprogrammed for the pto setting and that you are wanting to use your cruze control to up the idle speed.If you do not have cruze then you will have to find the right ecm wiring and install a switch In not sure on this, but im sure you could call your area dealer and find out..
