Unless someone has a Zenith apart might have to trace wires by the schematic:
http://www.nostalgiaair.org/Resources/455/M0025455.htm
Two large pins on the eye tube, 1 and 6, are filament, 6 volts and ground.
Pin #2 will only have a resistor going to pin #4.
Pin #3 is AVC line.
Pin #4 is B+.
Pin #5 is cathode and has a low voltage, near zero.

:GOS DAM IT!! As i carefullly pulled eye tube out of socket the wires came out of socket and I am not sure which one go back in where... could some one give me the color code for the pins... (white, black, red, blue, brown)
Best regards,
