what is on the horn circuit?

was installing my wideband, blindly used a razor to cut a hole for myself to feed the wires through to finish up the install and must have ended up cutting a couple wires that i shouldnt have. so in turn, my horn was blaring the whole way to work this morning. not fun.

for now i disconnected the fuse for the horn and its fine. nothing else seems to be affected by the short or the horn not being connected. is there anything else on that circuit that wont work because of the fuse being pulled? i am not familiar with the electrical drawings, so if someone could just post a link to those then i can look at it myself.

thanks in advance!

so really, if nothing else is shorting then i can pretty much leave the fuse pulled and call it a day.

Well unless I am drastically misreading that diagram, if you have On Star and pull the horn fuse, the BCM looses power too. But I would expect a host of other issues if that were the case, not the least of which would be a Security light on the dash since the BCM plays a role in reading the chip from your key.

i do not have onstar. my key does not have a chip either.

good to go, dont need the horn anyway since i never use it. if i find any other issues ill fix it, otherwise for now im just gonna leave the fuse pulled and live with it.

Who needs a horn in Wisconsin anyways?
