Why not use a relay between. Take a the switched power from some easy spot to wake up the relay and the actual power to your 5 + 5 Amps directly from battery thru that relay?

Well I have a number of loads. Which easy spot do you recommend?

This is based on not knowledge but trial and error from one of my first project cars something like 30-years ago... and I'm defenately not electrician

Here's the idea: Take the swiched power from a 'easy location' for your application that provide only the wake up current to the relay (could be done for example by wire jumper or cutting the original wire and soldering new wire and both old cable ends together) - this shoud be very minimal current for wake up the relay on your application, since the relay should be similar size as there already is in the car.
