Where is oxygen sensor socket?

[john318isau]

I discovered that after getting my clutch replaced by a workshop that they didn't reconnect what i assume is the oxygen sensor. there is a long wire with a 4-pin plug that isn't plugged into anything at present. I couldn't find any empty sockets -- can someone tell me where the oxygen sensor cable plugs into in the engine bay? Thanks.

Problem solved.

I found the oxygen sensor connection underneath where the battery usually resides if it is mounted at the front of the car.
