horn install
Hey.....I installed the same horns onto my 2000. I am unsure if the wiring is the same as the 2003, but, I just disconnected the battery on the positive side....spliced into the existing wires on the 4-runner and wired the horns to them. Be sure though to ground each horn...not just one of them or they wont work.
I know the instructions that came with them weren't written for someone who owns a 4Runner.
:upset:
But, once you have them installed they sound sweeeet...and LOUD!
Later,
