Hi, I have a diesel pickup with a hall effect sensor in line with the speedometer cable. It originally controlled the activation of an overdrive through the use of a control module (now gone) wired to a solenoid.
I would like a design (i'm sure it will be simpler than I think) for a speed sensing switch that can interpret the data from the current speed sensor, and act as a switch to come on at a certain speed and off at another speed. If both could be adjustable, that would be better. Something similar to this product:
MSD RPM Digital Activated Window Switch [MSD-8969] - $154.30 : Performance Parts - Ford Mustang - Cobra - Dodge Viper - Chevy Corvette - C6 - LS1
I don't necessarily need/want a digital readout, just an adjustable function. Basically, I need a 12v1a signal at 45mph, and off below that. Not sure what frequency that is on the hall effect sensor.
If anyone has any ideas, thank you!
