Im working on a 97 Prelude that has a 98 H22a4 engine and transmission standard implant. I cant find the plug location for the front primary o2 sensor. The rear is plugged in but there doesn't seem to be a plug for the front. If someone could help me with where the plug wires should be coming from off the harness or the pin locations in which plug would greatly help to get this CEL out. I have been looking locally to find one to look at but haven't been able to.
Oh and i love pics also if you have any, it just seems to explain things better.

 

The front and rear sensors are virtually identical - the cable on them is only about 8 inches long. Mine is a bit older, but there is a wiring harness on the back of the engine, just under the intake manifold. A 6 inch section of wire drops out of the harness just on the driver side of center under the manifold and goes to the connector. You might be able to get both hands on the thing if the car is on a lift, but with a jack, I had to disconnect and reconnect using one hand..... It required a bit of patience and a few bad words.

 

Thanks, thats what i thought. I think the wire got tucked up when the engine was installed to the point that it's not visible from lying under the car. UURRGG i guess ill put it up on the lift and do a little more digging.
