I can't give you a color code for the original wires because one does not appear to exist. It is not mentioned in Service Bulletin 5 (which covers the 511 Series), nor in the long form service manual for these sets, the Philco Radio Manual of Useful Information.
It appears that a majority of the 511 Series sets were made with the six-terminal resistor, and a separate 70K resistor mounted on the end of the chassis. With this setup, think of the terminals of the multi-section resistor as having terminals 1, 2, 3, 6, 7 and 8 with no connection between terminals 3 and 6. Terminals 4 and 5 make up the separate 70K resistor.
