Easy Way to Upgrade Horn?

:
2006 Tribute
2006 Mazda Tribute... puny horn... want to upgrade with a couple of Hella Supertones... but from everything I've read I have to take a lot of the front end covers apart to get to the old horn.

So... I don't care if the old horn stays where it is... I'll mount the new horns elsewhere... but I haven't been able to trace the horn wire from origin to destination at the original horn so that I can cut and splice to new horns.

Can anyone provide advice as to how to do this?

TIA
