Gauges Gas/RPMs/MPH/Temp

i bought one of them reverse glow gauges for my 2000 grandprix se an installed them not lookin anything up on the internet or whatever. an it didnt come with instructions.. but anyways when installing u have to remove the pins and i didnt mark where they were last at. an now they are all off .. ex. driving 40mph an it shows im going 90mph. so i was wonderin if theres a way to reset them or something.
