I've been trying to find instructions on which wires to tap into for my EGT and all i can find is the probe install, but they always leave out the part where i have to tap into the ignition wires and stuff.

its the greddy 52mm so the instructions are in japanese or something. anyways, anyone know or have a picture of which wires i need to tap into? thanks loads

Nevermind, i figured it out no thanks to you guys

for reference, the ORANGE and WHITE wires go together for an illumination souce (cig lighter or TT wire)

RED is constant power (theres a million sources for that)
BLACK is ground of course, just hook it to any metal part of the car thats grounded

 

the only thing i never figured out was the need for the red constant power....

 

the red is the actual power for the gauge and the sensor...

 

well the orange is ignition power ... which does the gauge and white does the illumination and black ground.....
