Default Need help wiring gaffrig tach

Older tachs says 1998 on the face, there are four wires red, black, green, white, coming through the back and no connection studs, these are monster gauges. Black ground, red ignition, white light, green tach? Ohming out the wires this is what I came up with. [ATTACH=CONFIG]519474[/ATTACH][ATTACH=CONFIG]519473[/ATTACH]
