I do have one as i bought it because i thought mine was bad but is was something else, i have heard conflicting stories about if they are compatible going from the srt6 to limited/base and vice versa. Someone on here said you cannot because he tried swapping but the guy working on my car a few months ago said it wont work until it is reprogrammed with the corresponding vehicles VIN. I paid $125 shipped and will sell it for that if u need it. If i remember correctly the dealership wanted approx. that much plus an extra 0 on the end.
