This bulletin has been amended. The Applied Vehicles have been updated. Please discard previous versions of this is bulletin.




This bulletin provides information to be shared with all affected customers.

^ This TSB contains the appropriate hookup points for connecting a trailer light wiring harness to the towing vehicle's electrical system.

^ The wiring diagrams contained in this bulletin are for Nissan vehicles that have trailer towing capability (see the owners manual) but do not have a Genuine Nissan accessory towing kit (with wiring) available.


^ When splicing into the vehicle electrical system, a power-type module/converter must be used to provide power for all trailer lighting. A power-type module/converter uses the vehicle battery as a direct power source for all trailer lights while using the vehicle taillight, stoplight, and turn signal circuits only as a signal source. (See the illustration above.) The module/converter must draw no more than 5 milliamps from the vehicle turn signal circuits and no more than 15 milliamps from the stop and tail light circuits.

Using a module/converter that exceeds these power requirements listed above may negatively affect the performance and function of the vehicle's electrical system.

See a professional trailer dealer or trailer rental agency for installation of the proper equipment.

Customers who inquire about towing should be reminded of the following:

^ Always check for correct operation of the turn signals, stoplights, and taillights every time a trailer is hitched up for towing.

^ The towing capacity for 350Z (Coupe Only), Altima, Maxima, and Sentra is 1,000 lbs.
