Do speed sensors wear out and wiring question

[Alexlind123]

Do speed sensors wear out (in the differential)?

and

Where do the wires from the fuel sender go (wheres the other end of them)?

Bump?

pretty sure they do wear out and/or get a bit dirty...sudden acceleration while on cruise control is a common symptom...

The 2 fuel tank wires end at the dash cluster.

the diff sensor can crap out with age, it's not a ac pluse generator it's a switch, you can test it with a multimeter set like you are testing a diode -I+ or -<+ is usually the picture for the setting
