78 SC need spark plug wire diagram

I am making progress.

I ammended my other post 78SC won't start.

I think the plug wires are installed wrong.

Does anyone have a diagram picture of how they should be installed?

I was told the firing order is 1 6 2 4 3 5

but which cylinder is which number?

and how do I know where #1 is on the distributor?

any pictures or diagrams?

Not sure on the dizzy, I'd have to check my book which is at home.

Arrow

From the back of the car as you are facing it the closest on the left bank is #1 then the next one is #2 the one farthest away from you is #3. on the right side the one closest is #4 then #5, I'll let you guess what the last one is.

3----6
2----5
1----4

The #1 on the distributor is over the hash mark which is only visible with the cap off. It is at the 4 O'clock position ok the cap.
