The only thing with the orange wire is that the 63 console appears to have a different color wire(s) in the picture
on the link I posted.
Also I have a 63 Assembly manual and on page 3 & 4 of Section Z03 at the back of the manual --it shows two lights for the 63 console(one in the console and one for the back seat) not like the 62 console with only the back seat light and
no ground on the 62 SS light.
The 63 SS console has the inside console light with a
ground to the floor and a push button switch to turn the inside the console light.
The back seat light wiring on the back of the 63 SS console appears to have two wires with no ground wire to the floor pan like my 62 SS console .
To summarize it appears to me that there are 3 wires in the 63 SS console for two lights + a ground wire and 2 sockets for both lights and the push button to turn on/and off --the inside the console light.
I would suggest to just buy the correct 63 SS console harness.
You could call or e-mail Ameican Autowire (see the link below)to ask them about the wire set (picture of the harness) or advise to answer your question. They have answered my questions when I ask. typcially I have the correct harnesses to make everything work correctly.
