O2 sensor connection
Had the car for a couple of months. Went to change the oil and found the O2 sensor wire tie wrapped and not connected. Can someone tell me where exactly this plugs into? physical location? Car has not been running for long. I got it on a trailer and have changed the injectors and distributor already. Car idles very rough, probably because this has been disconnected. The wire is too short to run up into the engine bay. Help please

Re: O2 sensor connection
The mating connector for the O2 sensor comes out of the wire harness bundle that runs along the lower left (driver) side of the engine compartment below the power brake booster.
If it doesn't reach, it might not be the correct sensor for your vehicle.
