What part of harness you will recommend to change first? Engine harness, injector or front part of main? What symptoms of bad piston, liners etc? Is only a blow-by is indicate this?

If the wiring is original, I would say replace it all from the firewall out. I have no clue on availability for a 570, I'm assuming it is an early 2000 model tractor, so wiring is around 20 years old. I have a 2008, and have kicked the idea around of purchasing the harnesses now while available and storing until the OEM wiring starts failing on me, which it eventually will, especially in Michigan with our weather.
