Vauxhall Tigra head unit installation



i have fitted a jvc head unit in to a Vauxhall Tigra but when i turn the ignition off the radio loses its presets. i think i need to switch a couple of wires around but not 100% sure what ones to change. anyone got any advice?

The red & yellow need to be switched. With luck you'll have bullet connectors in the loom to make this easy.
