05 Town and Country O2 sensor

I'm getting ODBII codes P0132 and P0032 which come back to an O2 sensor. In my case I think its the bank 1 O2 sensor on the front of the engine block. A neighbor showed me where it was but said the wire that is supposed to be attached to it is missing. Can someone tell me where that wire is supposed to come from? I con't see anything just hanging down anywhere.

Are you sure you saw an O2 sensor in front of the engine? Assuming you have a 3.3 or 3.8, (I don't think the 05's came with a 4-cylinder) the upstream 02 sensor is on the exhaust manifold between the engine and the firewall.
