You didn't say what year Buick but anything 96+ the PCM is under the hood.

Have someone who knows what they are doing reprogram it. It is less expensive and they will do it right the first time. Traction control? BCM interface? Correct the VSS input so your speedometer reads accurately? You don't want the MIL light on all the time.
You don't need anything under dash other than the OBD2 connector.
If you are interested I do build plug and play swap harnesses - http://reddevilriver,com
