The module is on the front of the Dizzy it is black and about 2 x 2 x 1/2 inches. The correct module will have E12-80 stamped onto it.
1979, 1980 and 1981 280ZX N/A and 810 (E12-80 Nissan # 22020-S6701)
1982 and 1983 280ZX N/A (E12-92 Nissan # 22020-W3100 or E12-93 Nissan # 22020-P9700)
You can use any Hitachi Dizzy from 79 - 83 BUT you must use the E12-80 ignition module.
Dizzy's from manual transmission cars have a total of 17 degrees of mechanical advance.
Dizzy's from automatic transmission cars have a total of 18 degrees of mechanical advance.
If you use the Dizzy from an auto trans car you should use the vacuum advance from a manual trans car.
Standard Motor Products has a replacement Vacuum Control # VC-351
The dual port vacuum advance unit is for automatic transmission vehicles.
Sorry, no picture.
