Chosen Solution

I wanna wire up a new horn, but I can’t find where the horn is so i’ve just been aimlessly trying to find where it would be wired up.

Can you try honking and follow the noise? They are usually somewhere in the front, probably between the radiator and grill bolted on to one of the radiator core supports. I think I’ve seen it not too far from the hood latch on a similar truck.
