I'm undertaking the Dynatek CFI 'Weber look' EFI conversion on my '66. I need a 12v ignition switched power feed that provides 12v while cranking the engine over, to feed the ECU . Any suggestions ?

Your best bet is to tap into the wire directly off the back of the ignition switch.

Thanks for your reply. My multimeter gives me a maximum of 9.6 volts off any power feed coming off the back of the ignition switch when cranking the engine over. I'm not talking about only the pink resistor wire here, I'm talking about all the power wires off the ignition switch. Is this usual ?

Use a relay from any switched wire and wire the relay straight to the battery. Don't forget to fuse it.
