I've installed some led daytime running lights on my A3, I have connected the negative wires to the negative side of the battery as the instructions said.

The positive wires are too short, as I was going to connect them up to the ignition switch wire behind the radio, so wondering what cable I could use to extend the positive wires?

Failing that they are long enough to connect up to my side lights, but I'm unsure where to locate my sidelight cables and which wire to connect them too?

Any help will be grateful 👍🏻
