Nissan 240SX Vacuum Diagram Q. I need a vacuum diagram for a 1992 Nissan 240SX DOHC. Thanks...

A. The diagram you need depends on the vehicle. To find your particular vehicle certification you will need to check the market application label.

The market application label is located at the top of the firewall in the engine compartment (this is not the V.I.N. plate). It identifies emission system certification (Canada, 49 state or California standards).

Once you have this information you can go to your public library and in the reference section you will be able to find the diagram you need.
