Hitachi 2V is listed for the 323 1.5Ltr E5 engine (1981-1985).

The Mazda 323 of that time from had a 1600cc engine but that isn't going to effect the issue of where to get a wiring diagram. Haynes makes a manual for the 1990-1994 Mazda 323. If you have a 1986-1989 Mazda 323, you will need to get a FSM (Factory Service Manual).
