Pathetic single tone horn upgrade

Took delivery of the car a few weeks ago and couldn't believe how pathetic the horn was. Ended up ordering a twin Hella kit with splitter wire included and looked for some guidance on best way to replace the roadrunner sound installed. Mostly worked it out myself but thought I could help others. Firstly, it's located behind the bumper on the nearside (UK model) and the easiest way is to remove the fog light. Use a trim removal tool and gently prise the trim around the light out from the bumper, starting nearest to the centre of the car. Prise the rest of it out working towards the wheel, be careful with the last part as the clips on this bit pull towards the front of the car. Then remove the 3 torx bolts (T25) from the fog light and pull the light out, remove the wire connection and place it out of the way. The original horn is clearly visible in the gap. This can be removed with a 13mm socket and the wire disconnected. Clip the splitter wire into the original harness, plug in the new horns and test to make sure they work! Bolt the bracket to each new horn and mount with the original 13mm bolt through both of the new brackets. Make sure they are positioned out of the way so that your fog light has room to go back in and cable tie the new wires out of the way so they can't jiggle about. Replace the light by plugging it back in and tightening the 3 screws to hold it in place. Push the trim back into place and test that fog light and horns still work.

Hope this helps, took me around half an hour.
