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?

sorry long day, its an sr20det, red top. when looking at the o2 sensor, there is a wire and it gos no where, no plug no other wire that i can see where whould i go from here?? thanks and sorry for the spelling..

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.
