Well first fix the wreck and make sure you replace the sensors up front. Then you need to replace the bags along with the control box. the Steeering wheel bag has 4 screws on the back side of the steeringwheel and Make sure the battery is disconnected first. then the dash one replaces after you pull the top dash pad I beleve then take out the bolts that hold it in. Its not bad just locating the control box is the hard part.
Well I have school tomorrow and they GM SI on they computers. I guess that will give me a better understanding of where everything is located. Thanks a bunch Michael.
