Hooked on Phonics.

Seriously dude reread your sentences before posting.

What engine is it?

from what i can translate, O2 is missing wires? replace O2 and locate O2 plug on the engine harness...then plug in

Is it for a wideband or for the ecu?

hmm well you should acutally have three wires comming out of the O2 sensor
the plug should be right behind the head or close to the #4 cylinder on the intake manifold comming out of the main harness, should be a grayish oval plug

ok will look again for the plug. but there is no plug on the o2 sensor should i just get a new one? also if there is no plug behind the head will i have to re-wire it from the ecu?? thanks for the help.
