There are two support rods that attach to the bottom of the dash then extend down to support the steering column. When I installed my reproduction dash harness, I routed it on the FORWARD side of these two rods(toward the front of the car). Later on I learned that there is a white plastic retainer built into the body of the harness that snaps into a hole in the back of the gauge cluster , which would seem to require the harness to be routed on the BACK side of these two rods(toward the rear of the car). Does that sound correct?

Facing the dash the harness runs on the LH side of the column.
The harness is forward of the support brace-rods.
Then, tight up across the top of the gauge housing.
IIRC, the plastic retainer snaps in above the speedo.

Appreciate the info and pictures.

Don't know if it will help you, but here is what the wiring in my '66 looked like. I used the American Autowire classic update harness kit.
