Received and installed the tailgate tie-down by @Lane. Definitely nice to have that anchor point usable again.
Also dug into my to-do boxes and finally attached the MAVERICK letters on the tailgate.
Occasionally get this too. Sometimes our grown daughter sits too far over from the passenger side seat and sets it off. This messes up both the PS and middle sensors.
My dad told me years ago that if there were three on each side it was a 6 cylinder engine in the car, four on each side was an 8 cylinder engine (originally an in-line 8 and later V-8). All derived from the early days with open engine bays and exposed exhaust manifolds and pipes.
