The information below was gleaned and posted VERBATIM from the MMC Handbooks and dealer parts books. However, it is subject to the following cautions.

A. The era from 1990 to 1998 has no published information. What we have been able to cobble together so far (below) reflects an ongoing GoMoG community project.

B. In the case of older cars, YOUR mog's 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 especially when you choose not to help us all and the Morgan Community with YOUR discoveries
. Additionally, if a stock componet was scarce at a certain moment or it was a model transition period, MMC staff would buy something/anything at the factor down the street.
 
C. If a modification after the parts or handbook was
published, this will not appear as the Factory does NOT re-print Handbooks or their regular Parts Manuals because of such a change.

D. Way older wiring methods were changed for a reason. They are unsafe by any standard. 35-50 amp fuses with their corroded wires under their insulation regularly cause fires and greatly diminish the fusebox as a diagnostic or safety component. This is not an area where originality should be admired if using the car is a priority.
