i search but came out with nothing. if u can link me up that would be kool.

i have a digital fuel pressure gauge. i have the sender unit all hook up. but i dont know how to wire anthing. there is for wires. red/black/blue/purple. i figure red=power, black=ground, blue =sender unit ( the unit has 2 wires that come out of it. a black n a blue) now i dont know where the purple one goes. any help would be nice.

 

come on guys. no body knows how to wire one of these up?

 

hate to state the obvious but have you tried contacting the manufacturer(autometer) here is the help section of their site
