I need help guys. I’m in the process of replacing my horns for a better sounding one. The toyota parts catalog shows it has two horns. One behind the grill and the other one under the driver side headlights. I’ve been at it for a while and I didn’t see the one under the headlights. Could it be in a different location? Unplugged the center one and tried the horn…no sound. Does this mean there is only one horn for US versions?
