Picture 9 of 29 from Album DIY; MPG Sensitive Cruise Control
Here you can see the 2 wires that were soldered to the circuit board at DIP Switch #3, very important to leave that #3 switch in Off because you will be controlling it externally. Be careful not to overheat the board to prevent any distortion or melting of it. Try a very clean and fast approach, since this will not be conducting high amp, only logical gate signals of On or Off.
