so my mx3 temp gauge dont work, i have an aftermaket on it says i need to connect it to a signal wire.. were would i conect it?

by your coolant fill cap there should be 2 or 3 sensors (depending on year) the 1 wire sensor closet to the firewall is the one you want.

its a 93 so i got two so i wanna add it to the green one? and doe it still need to be conetcted aswell just tap it?

[mikeinaus]

if your gauge isnt working it doesnt really need to be connected anymore. the computer uses the other sensor for everything. one wire sensor is just for display.
