Back of gauge cluster wiring/bulb pic needed for my '66

[Rust-O-Matic]

Does anybody have a pic of the back of their instrument cluster that shows the correct locations for each of the light bulbs? I replaced the chopped up harness on mine, but there appears to be 2 more holes than there is bulbs, and I can't figure out which holes should have a bulb in them, and which 2 should be empty. I know where all of the specific bulbs go, turn signals, hi-beam, etc., I just can't figure out where the cluster lamps are supposed to go.

It's the stock cluster from my '66 C20 with gauges (not idiot lights), for reference. I have been following along with the info in this thread here:

But the pics he shows of the back of the cluster do not appear to be correct. For example, his left turn signal bulb (blue wire on the right in the picture of the back) is definitely in the wrong hole.

Any help is appreciated.
