Study the following page 19/33. I'll get back to you later this weekend if you have questions. The most important thing you have to check and then doublecheck is your ignition coils. They should never have 12v pos hooked to them.That will fry your coils and could be expensive. Grd is hooked up from the keyswitch and that kills the engine. Again, take your time and I'll check back this weekend Also, don't lose this page because it took me forever to locate it.
