Hi
I am trying to wire air horns to my disco 2.I have read that you can wire them by using the original wiring from the horns is this the case?
I have wired them using a 4pole relay from the battery.
using pin 87 to the + side of the compresser and the - to ground earth.
pins 86 and 30 I have linked together on the rely and via a fuse to the battery + side.
pin 85 I have put on the original wire that goes to the horn there are 2 of them one is black that goes to earth and One is coloured purple and green when you put a meter on it and press the horn button in the car you get 12v and nothing when you let go.
so it sends 12 volts down to the relay
if I connect it this way the air horns go off and don't stop unless you disconnect from the relay can anyone see what I am doing wrong If any one can help that would be great
Thanks martin
