Reminds me of changing out the plug wires on my 89 Taurus SHO at the same time I replaced the timing belt. Didn't think I needed to take notes since I had a Chilton's.
I should've taken notes. Of course, the car wouldn't run. There were essentially two different diagrams for the spark plug wiring on that engine and one of them was wrong. I found the second (correct) one only after I took the valve covers back off and figured out the firing order on my own based on the positioning of cam lobes as I turned the engine over by hand.
Now I've got a factory service manual for that car.
And that was an expensive set of plug wires. Yet another expensive item I bought for that car BEFORE I ended up with a parts car with every single part, in excellent condition, I've ever bought for the one I was driving.
Learned my lesson and as soon as I got the 94 SHO for my daughter, immediately started looking for a parts car and found one with only 85k miles that'd been wrecked and nearly every part but some body panels and the front suspension is in perfect condition.
