The is 100% not OEM. Pull your carpet and trace where it goes. Just noticed you are in Ottawa. If you want, DM me and I will take a look for you, I am in Kanata. I install kill switches into JLs for free. Also check out OJC FB group.
I think this cable is stock/OEM .. it runs from underneath the sealed carpet up under the seat...it may have just come off / disconnected with all the crap that's been under the seat? I have leather / heated seats, may have something to do with that, although the seat heats up.
Also having a fuel sensor issue , fuel level always showing empty and check engine light on, but runs fine, scanner showing P0463 error, wasn't sure if this would have anything to do with that.
