Blue Truck Parts

  The Ford truck line fro 1987 to 1991, which includes F150, F250, F350 and Bronco's, used a full set of gauges that included oil pressure and voltage gauges.  Unfortunately half way through the production run Ford hobbled the oil pressure gauge turning it into a glorified indicator light.  Sensor vs Switch Typical Oil Pressure Sensor The 1987 to 1988 trucks included a fully functional oil pressure gauge.  They used an engine mounted oil pressure sensor that sends a variable resistance signal to drive the gauge.  The sensor is grounded to the engine block.  When oil pressure is low the signal wire will show roughly 100 plus ohms to ground which causes the gauge needle read low.  The resistance drops as the oil pressure increases.  Under normal operating conditions the sender will show roughly 20 ohms causing the gauge to read a little over half way.  It's not a precise system, but it works. Typical Oil Pressure Switch Starting in 1989 Ford replaced the oil pressure sensor with

 I got a message from a customer asking about the location of the holes for mounting the tailgate trim panel.  They wanted to mount a panel on a tailgate that did not originally have one.  These pictures will help document where the holes are on the tailgate.   The back/outside of the tailgate has 6 holes for the Blue Truck Parts Tailgate Brackets (yes, that was a shameless plug for our product).  Each hole is about 3/4" diameter to accommodate the base of the bracket posts. Measuring from the left side of the tailgate to the first set of holes. The middle holes measured from the left side. The right side holes when measured from the left edge.  The bottom row of holes measured from the bottom edge of the tailgate. The top row of hoes measured from the bottom edge. The tailgate also has two sets of 1/4" holes on the edges.  Small threaded trim clips mounted to the back of the panel run through them.  They are held in place with acorn nuts on the inside tailgate flange.
