i had originally posted a thread about the horn not working in my car after i put a ap1 wheel in my car, but i actually recall that it stopped working after i did my swap...i put a jdm itr swap with a hasport wire harness and as soon as i started the car the horn stopped... i put in a new relay yesterday and it still doesn’t work...any help is appreciated

 

check the fuse?
check the wires..
rerun wires...you dont even need it anyways...
get a train horn like and bolt the trumpets under the trunk drvr side and bolt the tank an compressor in the trunk
