OK Jerry we get it. You think I should be using a 900 and not the 700. Well, I'm not and to keep banging that drum is not helping. If I was that interested in doing everything better, I'd just go out and get a 2025 Chevy 3500 and be done with it. But that pretty much misses the point, doesn't it?

To trace the circuits, I disassembled one of my 700's. What I found looks different from what Walter shows earlier in his photos.

The picture below shows a left turn selected. Only two contacts being made (at 1 o'clock and 7 o'clock).

At this point, there are a few things I'm not sure about:

a. Not sure I understand why I need to care about the pilot bulbs? They will do what they do when they need to do it.
b. Not sure why we care about what's going on inside the 700. We know that if we run current to it, we will get 4 discrete lines out -- Two for the right and two for the left
c. Not sure why we care about the two wires for the front turn signals -- Just hook 'em up and ... done.
d. Leaving us with just two wires to sort out -- left and right rear turn signals
e. The problem then is how to combine the signal coming from the turn indicator switch with the signal coming from the brake light switch.
f. Then I'm not sure why it has to be this hard.
