    My airbag light turned on a few weeks ago and ran a scan which gave me the code.

    I got the dealer to pinpoint the issue as this code narrows it down to 3 options.

    I got the most expensive issue of course. It's the wiring harness. They determined it's an open in the wiring harness. The dealer told me that I need this part number:

    821615CL71

    Toyota Canada charges $2200 CAD for the wiring harness. After doing some looking around, I have a question. I notice that part was only used on the '12-'14 Prius C models. I know there really isn't much of a difference on the '15+ models...I mean not enough to change the design of a wiring harness....making me think that it's faulty since it was only used for three years.

    I'm looking for a second hand harness. My question is can someone provide an image or schematic of where part number 821615CL71 is under the drivers seat?

    I just want to see what it looks like so I can describe it to an auto salvage yard.

    could it be rodents? have you looked to see if it can be repaired?

    on the harness, when did they add the charge point under the hood? that might be the difference.

    I wondered the same thing about rodents.. but I think the harness is entirely inside the car. The dealer said that the open could be anywhere and that it would take quite a bit of troubleshooting. I read and heard that replacing this is a ten hour job.

    When you google that part number it shows up as Wire Floor - Toyota (82161-5CL71). I also wish we could actually see what it looks like because I would want to at least check the plastic electrical connections first (if accessible), maybe reseat them before a full replacement. Of course assuming no sign of rodents like Bisco said.

    I ordered it a couple days ago from Sparks Toyota in Myrtle Beach. The fed ex tracking number says it only weighs 8lbs. Toyota Canada should be ashamed they charge $2200+tax for the part. I am getting it for $1075 CAD shipped to Nova Scotia...even with duty it should still be half price.

    Now I need to decide to go to a dealer or a garage to install. Ten hour job.

    Has anyone ever had this part installed? What's involved?

    I think they charge by other characteristics than weight, mostly. :) Some big bulky things are expensive just for the space they take up on ships and in warehouses. Wiring harnesses aren't heavy or bulky, they roll up sort of well, but they're danged intricate.

    You will likely have out the seats, carpet, low interior trim and kick panels, center console, etc. Then it's just a matter of following the harness around, undoing all the connectors (there are pictures in the wiring diagram showing how all the different connector release arrangements work; some are more obvious than others) and undoing all of the really, really irritating little push clips that secure the wire harness in place. (Often that goes more easily if you have some kind of skinny, bent-long-nose pliers to get under the clips and squeeze the squeezy bits, but once you get the hang of one kind of clip, it changes to another kind for the next two feet.)

    Toyota got wise to the needs of material separation when recycling cars, and started bundling a length of aircraft cable in with all the electrical wires, with a loop somewhere in the middle. At a breaker yard somebody can just hook a chain to the loop and pull out the whole wire harness with a good yank from an excavator bucket, instead of having to pay people to pop out a zillion irritating little clips. That's only when you don't plan to keep using the car, though.

    Maybe plug in that part number at McGeorge Toyota Parts website. Ditto for anything you're looking for. They don't ship to Canada, but still a good resource.

    You might be able to set up a mail-box just over the border in the States. We have set ups like that here in Vancouver, drive down to Blaine. I haven't done it, but was considering it.

    Huh, $670 (US):

    Ugh, see it's a long drive to Maine.

    Well I had to pay $150 import tax for a grand total of $1225 shipped to my door. Much better than the Canadian price...would've been $2530.

    I'm getting a garage that does full auto service to install it. One mechanic worked at Toyota before...then I just have to get the seats calibrated....or they may get it done. I won't be able to get this done until May as they're very busy.

    The part came in two days ago. It's quite the bundle of wires. Lol. I can't get it installed until May...it's a busy time this time of year with many switching to all season tires.
