02 Signal sensor wire

from the upstream 02 sensor there are 4 wires just real quick what color is the signal sensor for a 96 RS.
cause i dont want to make little slits in the wire then test them all with the car on and the haynes manual didnt really help with it so if anybody can tell me what color it is.

If this is for a front o2 voltage gauge (AFR guage) you might as well make the connection at the ECU under the dash. This only applies for the turbo car, which one are you doing this on? And if its for some other reason, disregard this post, I dont know what the colors are at the sensor, never had to find out. :)

haha thanks i already got it though. i just checked each wire then connected it to the wire after it went in to the wireing harness all the way around the valve cover. i just thought somebody could tell me so i didnt have to cut a slit in each wire and test it.

also how do you find out what wire it is at the ECU?
