Nissan produced a wide range of variations on the Ignition Control Units it used in 70-78 Z cars. Now, many years later, these now out of production ICUs are failing at an increasing rate. Below is a chart to help owners of different models to better understand what units fit a certain production date range of Z cars.
ZPARTS.COM still has a decent amount of many different units in its inventory in USED condition. If you are in need of one, please email Eric with number printed on your car’s unit and I will reply with an availibility & quote reply. Part numbers in BLUE text link to online Ads for select units. More types will be added in coming months.
