This thread is for installation and calibration instructions for the S550/GT350 Mustangs. I have mine sitting here and plan to install it the weekend before Easter. I'll install mine in the coin tray to the left of the steering column and run the cable out the back. For anyone installing an AB I recommend that you remove the drivers seat to give you better access to under the dash. The seat comes out easily with four T-50 Torx bolts that use 35 ft lbs of torque when reinstalling. Please remember to disconnect your battery before removing the seat. Ford now uses one connector under the seat instead of two and the S550 seat is easier to remove than the S197 seat. Also place a towel or old blanket over your door sill so you don't scratch it when lifting the seat out.
