Shop manuals used to contain full wiring diagrams, but newer ones often just say the diagrams are so complicated they are not included. In my experience, dealer parts departments will often provide copies of portions of wiring diagrams free, particularly if you ask nicely. Online forums for your specific vehicle often will provide this as well. Is there some specific issue we might help with?

Your ignition timing may have advanced too far. Or it is now where it should be and is making more cylinder pressure during combustion causing the gasoline to ignite to early causing detonation or ping.
Make sure the ignition timing is correct. If it is try better fuel meaning the octane rating.
If you can go up to the next octane level. For example if you are using 87 go to 89 and see if it goes away. 3 of my wife's last cars a 1986 Honda Prelude, 2000 Neon, and a 2003 Neon had some ping under medium to hard acceleration. She switched to 89 octane and the ping went away completely in each vehicle. Each of the vehicle had a good deal of miles on them.
The 2003 Neon has 75000 miles on it now and runs great on 89 octane. About a year ago I tried 87 Octane in her car and the ping came right back.
