Hi all potentially looking for a trigger for an arduino so thought id use a switch live on a relay.

As the arduino will be living near the fuse box I’ve taken a peak and there’s a fair few red with black stripes are they all switch lives?

Can't help but curious about what you're doing with an Arduino..? 2011 4.4 TDV8 Vogue SE - 'Black Betty'

Ive got a valved exhaust, I am planning to have a button to switch it to loud and quiet but this is where the Arduino comes in - Dynamic like the sir so its loud at idle then quietens down until 4000rpm... Current stable:
