So after getting my dads swift .we were not happy with
the peee peee of the horn 
We wanted POOM POOM:P
Here is the D.I.Y
since by profession i am an engineer so will have to bear with me the exact details .:*
I was able to do this just by looking at the workshop manual of swift .
- The tools required are
a Rachet socket set
b Wire cutter
c.Long nose plier
d.philips screw driver.
e.Flat head as well
f.And off course the new Horn set

2.Start by opening the hood and locating these red circled bolts (10 mm )
along with the two plastic clips circled blue (Use flat head screw driver to lift up)

- Also remove the screws located on the side of the bumpers (both sides)

- Remove these bolts form the down side of the bumper (10 mm bolts) (3 of them )
along with plastic clips (4 of them)

- Now detach the sides of the bumpers (just pull them ,they will come out)


- After that just lift the bumper up a little bit and it will be free form the structure .
There you go your car's bumper is removed.

- There is the suzuki PEEEE PEEEE

- Remove the horn from structure using a 12 mm rachet socket.Like this
disconnect and cut the cable from the connector as well. you wount need it .

9.New Horn set (XLI 2012, Full power tone LOW and HIGH ) RS 1350

10.Use the diagram which comes with the horn set to identify the wires
(short cut ,There is only one wire present which is powered by a relay inbuilt into the swift , so just use it for connecting the two ends of the horns make it common)
And the other common would be the chasis which is the return )
Note: Carefully watch the diagrams



There it si Your swift's horn is ready for POM POM
I Absolutely love the way it sound now :*
Kindly go in reverse order to assemble the bumper back (H)
HAPPY POM POM
