I'll fill this in later. The "book" I typed in this field before didn't save. Come back later if you want to read more about the theories behind porting and polishing.

READ A LITTLE :This has been a 4 year long story on & going even to this day, the pos owes my moms work plenty of money and they worked something out to fix my car to cover some of his interest on the machines he got from her work. He has not touched it as you can see in probably 2 years. The engine got pulled in the first week..it was suppose to be done within 3 months lol. Btw that wire is 2 g not 0!
