Would this happen to be a stage 3 front bumper? If so, it does not come with any of the wiring, I'd recommend buying a harness from vmptuning.com, it will make your life much easier. Once you get that harness, you will have to pull off the gt connector on the end and put on the roush connector. This involves taking a pair of needle nose pliars and pulling up on the metal connectors, turning them 180 degrees and pushing them out of the connector. Then reverse this for putting the wires in the roush connectors.
