Does anyone know what the five wires on the pre-cat O2 sensor are? I'm trying to put in a universal, I know I should have gone with the OEM, but I'm cheap what can I say.

Red =
White =
Yellow =
Gray =

Thanks,

i wired a switch in the cigarette lighter hole so i could manually turn it off while driving. but i goes off when i turn off the ignition as well.
