02 sensor issue

[PjctWhiteNotch]

my 02 sensors are in the longtubes, but it runs up to the front under where the airbox would be with a little plastic clip attached to the fender area (its a female connector black with red center) they are not hooked up and can't find what it hooks up to. there is no smog pump if that might be an issue.

any info would be in a great help

if ur car has mass air from the factory i think its in along the same harness as the maf sensor......u should see a thick black plastic wire cover going up and over the passenger strut tower that comes out of the passener side firewall (the computer is back there) and should go down to the fender n connect to the harness that goes to each 02 sensor and the low oil level sensor also like ur talkin about

there are 3 connectors not in use on the passanger side,but none fit o2 sensors.is there a chance that the o2 sensor wires are different when put in and do not fit the factory harness?

i know theres a wiring schematic on here somewhere of the 02 harness...i think it was linked by Jrichker off autozones site, i forget...anyways......u got two 02 sensors....and an 02 sensor harness, total it has 3 black male/female connections, 2 of them go to each 02 sensor pigtail and the other connection connects to the car harness which should be by the passenger fender under the intake tube (the oil level sensor also joins into this main harness too), which combines the 2 02 sensor wires and the low oil level sensor wire into one connector that plugs into the harness by the fender so it can send all the info to the computer
