Radio wiring colours

[Johntom]

Hi
I’ve just bought a 63reg custom with a non working radio/cd so I decided to upgrade to a touch screen/reverse camera etc. I’ve bought the connect2 looms etc but the new head unit doesn’t power up (works direct from another battery) so I’ve tested the wires and have a negative and permanent live but no ignition live ? Does anyone know what colour it would be going into the standard ford plug ?
Thanks

Is this any help?
