Help asap engine wiring

[addam111]

So My friends were trying to pull a joke by installing an aftermarket horn using a relay but they hooked it up the wrong way and it fried the wires to the ground of the horn, so I tried to repair the harness but I'm getting an engine code implying that the coolant circuit is high( whitch is the same harness I do believe. Also I misplaced the barcode connected to this harness and can not find the part anywhere, could somone please help me find this part online. It's the harness that plugs into the bottom right of the fuse box
It's for a 12 hatch 1.8L

Skip the dealer, but still take your friends credit card and make good use of it.

what the hell were your "friends" thinking, you don't mess with another persons car with out permission, that's a good way for someone to get hurt. its could be possible that during this harness meltdown it harmed an important system, and or rendered a safety system inoperable, these cars are highly computerized meaning its possible they burnt out part of the bcm that you wouldn't be able to diagnose easily at home, this is assuming the bcm controls the horn. which i wouldn't be surprised if it didn't.

i personally would take it to the dealer and have them repair it since it could prove difficult for the home mechanic to diagnose the extent of the damage fully. and of course make you dumb ass "friends" pay for it.

just my 2 cents on the subject, i wish you the best of luck fixing the damage to your car.

if they managed to melt the harness, i doubt it was properly fused. :blankface:
