ABS line cut - must replace engine wire harness?

Recently I lent someone my car. They had to drive in snow so they put on snow chains. Whatever happened, the chains snapped and did quite some damage to the surrounding area on the front driver side.

The most expensive damage is severing the ABS line. Dealer and local shops said I can't just patch the wire, which is shielded, and I'd have to replace the entire engine wire harness, which retails for $4000+ but I can find it for a few hundred salvaged. However, it's supposedly roughly 25 hours of labor (which I believe, being that thing looks to connect to everything - the entire fuse box is part of it), which labor itself would cost $4000+.

Anyone happen to know if it's possible to replace just the severed lines if I have the entire replacement engine wire harness?

The ABS is at stake here so I take it the recommendation is to do a proper replacement (at $4k+) than me practicing my soldering skills...

(Might also mention, the wheel speed sensor was also severed, but the replacement for that seems much cheaper and I don't mind paying to just get fixed straight up.)

 

I don't know for sure whether they put the chains on incorrectly. The chains were unused, I myself had never put on and used chains before. To my knowledge I purchased chains correctly sized for the stock size tires on my car. For all I know, the same thing could have happened to me. The person said they followed the directions that came with the chains. I'm not saying for sure they didn't do anything wrong but they're a family member and I don't think they were being reckless or negligent or hiding anything. We're still open to discussing who pays for what, but meanwhile I'd like to avoid anyone selling out thousands if it can be avoided.

 

This would be from a normal OBD scanner, or Dr. Prius, or that software thing that runs on Windows 7 (forgot what it's called) - I have access to all.

 

Thanks everyone! What I'm hearing is "it's actually possible to splice shielded cable, so do that".
I already ordered the whole wire harness off eBay (salvaged) yesterday for less than $300 so once that gets in, I'll see if I can just cut off the whole ABS wire and splice it to the damaged wire. In hindsight I probably could've just spliced in some other shielded wire and not have bought the entire wire harness, but if I can actually get this to work, I'll just be happy to have saved the $9000+ it would've cost for the dealer or the local shop to fix this.

 

It's not just the speed sensor though - it's apparently some additional wire that's part of the main engine wire harness. ABS sensor I believe, but I don't know for sure since I don't know what parts are what. If it was just the speed sensor, I would just replace it completely as that job was quoted much less.

 

I haven't even tried taking a close look at the damage so I'm coming in to this with zero idea of what's in there (and sorry I don't know how to read the diagram you included earlier), but it sounds like ABS/speed sensor is one and the same, which is connected via its own wire (the one you posted pics of) - and that wire is connected to a branch coming from the engine wire harness (assuming the mechanics are right about damage to the engine wire harness)?

As in, it's multiple components connected in series that are damaged - but they all lead to one ABS/speed sensor - as opposed to a speed sensor and wire being damaged, and some other ABS component/wire in parallel that also got damaged?

(These are the two electrical part numbers/links the dealership said I needed to replace - engine wire harness, speed sensor. I already ordered both for much cheaper salvaged off eBay.)

 

The dealer actually sent a short video - attached a couple stills. Now that I've watched a YT video on replacing the speed sensor, I now recognize one of the stills featuring a completely severed wire that I'm pretty confident is the speed sensor wire.

The other still features what I'm guessing is part of the engine wire harness. The jacket has been chewed through but it's hard to tell what damage has been done to the actual wires. The shot was taken from next to the tire, facing forward. It's clearly separate from the speed sensor and I have no idea where those wires go (based on the video/still - I haven't tried following the wire in real life).
