DO NOT do a wholesale removal of the gauges and then wonder what wire goes where when you install the new ones. LABEL each wire as you remove it. And be sure you mark the wire with its actual function: Such as TACH = "I" (which is the ignition/+12 volt terminal). TACH GND , TACH "S" (send terminal). EAch of those connections on the gauges is marked on the housing. The terminals on the new gauges may not be in the same position as the old so don't use a picture and hope that the terminal on the far right, top, bottom or left is the same terminal on the new gauges.
