Default Opti Spark wiring

Does anyone know, have a picture, or diagram of how the plug wires connect to the Opti Spark unit, especially the drivers' side?

Replaced the wires and just want to make sure I have them correct.

Looking at it from the front. Top to bottom on the passenger side: 4, 6, 8, 2 : Driver side top to bottom: 5, 3, 7, 1.

The last one I put in had the numbers on the cap, a little hard to see after install though. I'm sure its in the book.

There's a spark plug wiring diagram label under the hood, at least there is on my '92.

When I built my 388 LT1 I used some bright RED fingernail polish and wrote the numbers on the face of the Opti to be able to see them once the engine was installed.

Even thought I had installed the plug wires before installing the engine I figured at some point down the road I'd need to know which plug wire goes where.
