The Mazda B2200 truck body did not change much, if at all between 1986 and 1993. There should be no differences in the shape of the engine compartment. -Kyrasis6 Owner of Mazdatruckin.com

I cannot find a photo on a 1992 Mazda 121 or the 1.3 engine. However I would suspect the firing order & connections would be the same as the 1.8L engine. I will post a link showing the connections on the 1992 1.8 L engine. Try this connection.
