Started to instal my horn back onto the car as I took them off when I did the front mount and need them back for the MOT. Stupidly I didn't take a photo when I took them apart. I have two blue wires with spade connections that I have traces back to a junction clip thing and I think they are for the alarm (this was installed by torque GT when imported). So my question is do I link these into the negative side or positive side of the horn. I've checked the wires and they are neither earth or positive so I assume they go one way or other when the alarm is activated.
