NOTE: I am not responsible for your actions, again do this at your own risk! I trust swapping the charge than wiring into the airbag system. I only swapped bc my charge only had one plug in the back, and is single stage and the 08 is dual stage.
This is very simple. Unbolt the 4 10mm bolts, carefully lift out the charge, and place it into the 08 airbag.
now if everything is good, you can reconnect the airbag. REMEMBER TO DISCONNECT THE BATTERY AGAIN AND WAIT, DON’T BLOW YOURSELF UP
reconnect everything…. Your done! Again once you get everything back together check to make sure it all works.
