The best one is in the shop manual. There are two different shop manuals depending the vintage of the tractor. Preside console or side console (split at 201,000). There is a fair on in the parts catalog and a poor one in the I&T manual. There are actually several in the early 4020 parts catalog because there were at least three variations on the wiring harnesses and connectors plus the variations for engine fuel.
