Ever since I have had my glanza ive had no horn. So I bought one but Im struggling to fit it to the standard set up. I took me an age to find the horn. Am I correct in thinking the is behind the driver side head light? The reason I ask this is because I have found what seems to be a horn or alarm there that doesnt work and only has one wire going to it (but the wire in the back of the steering wheel joins to one) which makes me think this is the horn. I have also found a spare plug with two wire going into it near the rad. Testing both these with a multi meter reads blank when horn is pressed. Can someone point me in the right direction? Thanks Brian
