I am working on a 3x comfort turn signal project and am looking for a detailed diagram of the switch interworking.

I am fairly close to getting this to work, I think, but believe I need a diode or two to be successful. Below is what I have from an ebody wiring diagram, which isn't all that helpful.

That image was from page 8-95 and only shows half.  Look at the other page of where that image was taken and you'll see where all the wires go.  Look for page 8-94. (Click to enlarge the photos)

Just print both those pages and put them together.  You'll need to follow the wires back and forth from each page.

Thanks Cody.

I was trying to see just how the internals of the switch are working, I have a theory but a diagram would help confirm.

For example
the turn signal flasher power comes into the switch as a single wire.

If i turn left, the switch should internally connect the flasher wire to the left front and rear wires, but not the right side.

The right side stays connected to the brake circuit and doesn't flash.

Trying to understand those relationships.

You have it basically correct
Power is fed through the flasher into the switch , from there it connects the power to 4 outgoing wires , 2 for the left & 2 for the right  , for example 2 for  the front left & rear left , they are separated so the brake light circuit doesn't light the front light when the brakes are applied , only the rear light which is interupted .  The brake lights always go through the turn signal switch & come out on 2 separate wires so only 1 is interupted with the turn signal .
Hazard lights use a separate flasher & power into the switch & using a different switch inside the turn signal switch inside the turn signal switch connect all 4 lights at once .
I hope this helps  :bigthumb:

Hope this helps.  I took an ASCII drawing JS Restorations put up and created a cleaner PDF for it.  I'd like to do that same for the Ignition switch if anybody has something similar as a starting point.
