does anyone know of a tech page or somethang that shows (in good detail) how to install aftermarket gauges like fuel, voltmeter, water temp. on a 2g?? I searched this forum and came up with nothing. Thanks in advance

Is your stock fuel gauge not accurate or something?? i dont see why you need an aftermarket fuel gauge. How bout oil psi or A/F gauge or something? or are you talking about an air fuel gauge?
But for the fuel gauge i would think you would have to connect the wire or what ever is on a fuel gauge to the float in the gas tank. That makes the most sense to me?

the gauges are easy to install, but a PITA. it's really time consuming to do everything, and make it right so you don't have 100 wires hanging everywhere. voltmeter is probably the easiest one to install. you have a power and ground for the backlight, and a power and ground for the gauge itself to function. water temp is easy. power and ground for backlight, and the signal wire that connects to the thermostat sensor (that you also have to replace, it comes with the gauge). i can't remember if there is a power/ground for the gauge itself to function. oil pressure, same thing except you're gonna get dirty considering you have to replace the oil sending unit. air/fuel is annoying IMO, but you connect the signal wire to the O2 sensor, power/ground, etc etc. then you need a gauge pillar for the gauges. running the wires are always fun from the gauges to their locations (sarcasm). then hiding them. then securing the pillar. then hoping you hooked everything up correctly. oh, and make sure to keep the wires that you run through the firewall away from mechanical parts. have fun :)
