The information below was taken VERBATIM from the MMC Handbooks and Dealer Parts books. However, it is subject to the following cautions.

A. The MMC did not publish wiring information from 1990 to 1998. Though I no longer have a Morgan of this era, there is a wide demand not let this era be orphaned. We have been cobbling together what we can. The diagrams reflect an ongoing GoMoG community project.

B. In the case of so many mogs, new and old,  your reality often reflects changes done to it over its lifetime. Wiring will have changed and the fuseboxes used differently. Please do not blame this on GoMoG. That is silly.  Those who point out anomalies publicly almost never report them to me.  Additionally, if a stock componet was scarce at a certain moment or it was a model transition period, MMC staff of the day would buy something/anything at the factor down the street.  These things are not reflected in the handbooks.
 
C. If a modification after the Parts or Owners handbook was printed, this will not appear.
