Chasing R32 Wiring Diagram / Install Airhorn

[Dizmo]

As topic states i am after the electrical wiring diagram of a R32 skyline. Would prefer one that has A/T since car used to be auto. I wanna hook up a horn, but switch between stock and airhorn. Wondering where to install switch and tap into. i preferably wanna do it under the dash away from the engine.

Any ideas and wiring diagrams plz

You need to use a "changeover" relay. Give me a bit of time and I'll think how too best work it, but I'm thinking it will simply switch where the current horn wire directs itself when you press the button.

wont take much just wire in full power to a relay from the bat hook it up to your air horn and earth it then hook the normal plug from the standard horn up to the relay also so when you press the horn button in the car it ticks the relay over to give straight power to the airhorn. easy
