Patrick Posted January 23, 2013 Report Share Posted January 23, 2013 Hi i'm wiring two digital inputs into my expansion loom dI5 and 6.Â DI5 will be a flex fuel sensor which will incorporate a 2k2 ohm pullup resistor to 5volts. For DI6 i want to make a switch to activate logging but unsure how to go about it, I came across this illustration in the pclink help file which is pretty self explanatory.Â What i dont understand is why it suggests a 14 volt pullup and not a 5 volt pullup like in the flex fuel example.Â In any case what do you suggest for my switch and the appropriate resistor to use.Â Also to activate datalogging on/off should i be using a momentary or toggle switch?
