Up and behind fuse box, blue box. Very hard to see when your head is under the dash. You got to depress the cluth petal, to get a better view. To remove the protective blue box, which has the module inside, two fuse box nuts should be removed, then push fuse box away. That will give you enough room for your hand to get thru, the box is hanging and is locked in place by a couple of taps. All I did was wriggle and pulled on the box and it loosened. Once it dropped near position of fuse box, remove the connectors. Two things to remember, 1) dis-connect negative on battery, and 2). Only Merc Sable, I got my off 91 sable, maybe 90or 92 too? I checked a lot of early 90s Ford models, the only one that is the same is the Sable. good luck and remove that tape
