Hello, I have searched the forums for the answer, but no luck. I just purchased a 1998 Mercury Sable LS Wagon and I am looking for the RCU. The car has the car phone package--the car phone is long gone. I found the car phone unit on the driver's side in the rear--it is just under the deck of the trunk between the side and where the third seat folds down. Either I am blind or I cannot find the RCU. Should it be right below the car phone unit? Thanks for the help!
