"18 RT wiring harness damage

Hello all,I recently had some rodent get into the underside of my 2018 RT and chew through a bit of rubber vent hose and worse, through a four-wire harness. The location of the wire break is just on the wiring harness side of the left side oxygen sensor wire (see photograph). I wanted to check to see if anybody has had experience with that as a repair at the plug or (God forbid),is this going to be a full replacement of the wiring harness?Thanks in advance!

Take a picture of the end of the plug/socket and I should be able to tell you what parts you need to repair and where to get at sensible prices. Most of BMWs connectors are made by TE Connectivity and can be bought from RS for a few quid each. Failing that you will be able to get a repair part from BMW for 20-30.
It looks like a straight forward repair

Thank you for the quick reply Graham. I've posted a couple of photos of the plug.

83300402337 is the bmw part number, i think these come with a flying lead that you can solder to which saves the crimping.

Yup ebay the P/N and you are looking at 30GBP.
I am 80% sure a drop in replacement is a TE MCON 1.2 which are 1.60 each plus contacts, from RS but I can't be sure as I haven't ordered one before. At least the BMW part doesn't need crimping.
