It's not a matter of that. It is a matter of learning the hard way for me. I did not read the rules and was quickly shown why you should. Also being able to download the factory service manual for free is invaluable. To be able to sit here..find the diagram..zoom in on it, or print just that page to take to the car with you instead of the whole book. It took me less than 5 minutes to search,find,download. Any year is available. I am clueless on electrical schematics. The FSM has drawings of each section of the wiring harness and also each plug is labeled as to what it is. I could not tell you where the download is(I forgot).
You can see under my avatar my "infraction" From not reading the rules and popping off when I thought an administrator was being mean. He was enforcing the "rules" of this forum.
