69″ 300 convertible speaker wire colours

Hi Guys,

Can anyone tell me what the speaker wire colours are and if it is a 2 prong or three prong plug.
I removed the entire dash for restoration and there were no speakers in the car at all, the radio was kaput and there was not a speaker wire going the rear. I have acquired an original good working radio and new speakers and laid in a new speaker wire for the rear. The entire floor was de rusted, rust converter and primer applied, full car insulation installed, new carpets, bucket seats rebuilt and now ready for all the dash to go in over the next few days. It is the first day of spring in Australia and this convertible is itching to get out of the shed!!! Aussie Bob
