Dash Harness ?

I have a question.

Working on a 70 Duster 340 Duster 4 speed, all manual no A/C, which from all signs is all original 340 car. No hacking or signs of substute or fabricated rally harness.

Rally dash socket does not have the wires colors per 70 schematic found on mymopar website http://www.mymopar.com/downloads/1970/70ValiantDusterB.JPG , or any other schematic I can find. I have already looked at other years between 66-71 and none match what I have. Other non-1970 year schematics also all consistently show the following wire colors and quantity,
-dark blue with trace,
-dark blue,
-orange,
-violet,
-red,
-light green,
-tan,
-grey and
-black.

But problem is my plug only has 8 wires and not all the same colors,
-dark blue with trace,
-dark blue,
-orange,
-violet,
-tan,
-black.

In addition, it has
-white, and
-black with trace.

But not present are the usual
-red,
-light green,
-tan, or
-grey

Hoping someone can help me figure out in what order the wires I do have should be placed in the socket, considering the wires can be placed in any sequence and location. I only have 8 wires to locate, and the socket has 11 slots in it.

Also the standard rally dash circuit board only has 8 pins, so knowing which color wire goes to which circuit board pin is ultimately what would allowing me to place the wire pin terminals in the corresponding socket position.

Thank you in advance for any help.
