89 F150 6 cyl 5 speed 4X4..may need to replace this switch. Does not make contact every time I depress the clutch pedal. When checking the electrical diagram, I can only find 4 wires. Ignition sw, start relay, distributor and pcm. The switch has 6 wires. Where do the others go?

 

Just a guess here but one could be the Clutch Pedal Position sensor and the other a ground
