I'm not sure EXACTLY what you are referring to by xfer pump or 'certain'
voltage. I designed a simple circuit (you can build for~$20) that uses a
return signal from any 5v referenced sensor (IE TPS, CLT, IAT, ect.)(0-5v
return) that can be infinitely adjusted (with hysteresis) and will control a
relay for MANY uses. With slight mods, could be used at any voltage level.
Any help?
