Mice and Engine Harnesses Don't Mix

Recommended Posts

2015 SE - 2.5L

 

So, see the attached picture, but basically, I had back surgery so I didn't drive for eight weeks. Do you know what a mouse can do in 8 weeks? Yep, decimate a wiring harness. And it drove like this just fine. I actually took it to my dealer for a warranty item prior to hitting my 36k and the mechanic found this.

 

Anyway, they're checking if there's any other impacted wiring, but it looks like the coil pack may be ok. So let's say it is just the wiring harness, are there any tricks to this? I'm competent enough mechanically, but I don't like snags and I need to avoid snags on this because it's my daily driver and my wife works Saturday and I need to transport the kids. It looks to be all electrical fittings, but I can't find a non-CAD image of this part so I don't know if any of the connections are "different." Any ideas on access issues or can I get it all from above and below?

 

Other question, is there anyway to not buy the whole harness and only buy the three connectors in this picture then pigtail into the existing harness? I can't find just the connector on any Ford parts websites.

 

And last question, if I go look up this harness on fordparts.com it shows the part number as 12A581. But if you google that number you get different variants. After confirming with the dealer based on my VIN I would actually order EU5Z-12A581-C. And there are other 12A581's that are not EU5Z. So does anybody know what the EU5Z represents? And it seems I could only find it by calling Ford, any other ways for different parts to do this in the future?

Holy pigtails! Thanks for the link.

 

That index is very thorough to quote the great Maude. I shall start searching for PN's.

The first letter refers to the year the part was first used. Currently, A=2010 and so on. The 2nd and 3rd letter identify which car line it is. The 4th letter identifies the engineering department responsible for the original design.

Holy rodents, Batman! That mouse did a real number! Glad to hear nothing major was impacted.
