I'm new here, but have seen on CJ PonyParts videos that there is a plug that can be pulled in a box under the trunk mat that will REMOVE the fake exhaust sound from the speakers. Does anybody know which plug (color/shape) to pull, and does there need to be a "blanking plug" to stop any weird check engine lights or something? Sorry if this subject has been covered countless times, but I didn't know where to look!
