Hello and welcome to the forum.

In all honesty you'd probably be better to take an ignition feed from the back of the switch (with an inline fuse) and run new wiring to the switch and horns,or even take a feed straight from the battery with an in line fuse near the battery and run the wires into the car to the switch and then to the horns.All you then need is a two pin horn,a feed from the switch to one pin and a body earth to the other one.

I'd be tempted to leave all the other wiring alone on the car as it can be a little sensitive and you might end up damaging the UCH unit.

I'd rather push my Alfa than drive a BMW....
