I just bought this 98 disco. The O2 sensor was not plugged in anything. I cannot find the correct plugin for it. Help

 

Upstream or downstream?

 

Before cat

 

That would be upstream. The plugs are located behind the coilpacks in the trans tunnel.

 

I got very intimate with my engine, I was on top this time, found nothing.
I'm going under her next time and see what I can see.
Is there a patch cord for the sensor wire, it's not very long.
Stretched out it barely reaches the edge of the valve cover

 

Nope, it's all you get and it'll reach the connector once you find it. You might have to remove the whole coil assembly to find the connector........ try not to get too intimate, you might end up with

 

Austin Healy frog or bug eyed sprite kind of

 

51' Crosley Super Sport micro. Just plain ol fugly.

 

As mentioned the Pre-CAT O2 connectors are near the firewall (see pic).

If you can't find the female ends of the connectors ( C112 & C113 ), then look for the wires.
The connectors and wire color pin-outs are below.





If this you might need ...….

 

Also mine has the four wires red, yellow, black and white.i wonder if I may have the wrong sensor. It was put in by the p.o.
Any thoughts on this
