How do I wire the plugs on my 95 Buick Century?

1995 BUICK CENTURY

I have a 6 Cyl 1995 Buick Century and I removed the spark plug wires without documenting them. (no, that wasn't a smart move on my part)

I'd like to replace them, but my chilton manual isn't very clear on which wires go where.

Here is a rough picture of my engine with small circles to indicate where the wires go from, and the large circles to indicate the cylinder the wires go to.

I am happy to draw the wires on later, number them, label it and upload the final picture for others to use.

You didn't say which engine you have for there are three different V6's that GM made that year. Here is what I have hope this helps. Sorry the 4 cylinder got in here

Thanks, the second to bottom one is the one I wound up going by loosly.

My coils were on the opposite side of the engine and rotated 180, so that confused me at first. (I have these diagrams in my Chilton manual for the vehicle.)

I have a 3.1 L V6, but I couldn't tell which to use at first because the drawing I wound up using had the coils on the opposite side of the engine.

Fortunately the previous owner (my father-in-law) had etched the firing order into the surface of the coils, and I just didn't notice it earlier, so I was able to match up the proper diagram.

I will post back with a drawing of what exactly I used, in case someone else has a similar setup.
