Alright, so my O2 sensor has been disconnected since i bought the truck. the previous owner just plain cut the wires. so here"s the situation: i have the plug still on the O2 sensor but the plug that comes from the harness is cut off. i need to know which wires go to which on the sensor.
from the harness there is:
a thick black one
brown
white w/ green stripe
white w/ red stripe

the O2 sensor has two blacks a blue and a white.
i don't know what to do here. should i just try to look for the plug at a junk yard? pretty much i just need to know what wire goes where. i've told you everything i know and i need help! it would be appreciated. thanks.
