Hi, I was an idiot and didn’t label where the ignition wires went before, I replaced them. I think I have it right, but I have found 3 different variations on where they go when trying to search online. Does anyone have a true diagram for me? Thanks

Sure, here you go this is how the spark plugs wire go on the engine and the firing order. Check out the images (below). Let us know if you need anything else.
