2004 nissan sentra, viper 5901

installing a viper 5901 onto a 2004 nissan sentra.

Im just trying to get all the parts that i will need to get a full install done on the car. So far I im going to get the viper 5901 system and a xk05(pkn2). Will i need any extra relays or modules?

and also i was wondering if i could just connect the pkn2 to the brain with just the d2d ports, would i still need to hardwire any other cables if i went this route?

This is a U.S. model, right? And is it a regular Sentra, or the sporty SE-R model?

Until 2006, only the SE-R got the immobilizer key option. All 2007-up Sentras have it now.

As long as your Sentra is a regular model, you didn't need to get the XK05....maybe you can return it?

The rest of the car is pretty straightforward, access to everything under the dash is easy, and you shouldn't need any extra parts.

The only thing you could possibly need, is if you want to wire up the (optional) feature to unlock only the driver's door on the first press of the remote, and then all the other doors on the second press.

For that, you'll need to buy one relay, and it's a little extra work to wire up. It would typically only add five or ten minutes to the install, but relays can be confusing for beginners.

The rest of the car is easy:

Ignition wires coming down steering column from ignition switch.

Trunk release and parking lights are at their respective switches on the dash.

Brake at the brake pedal switch.

Doorlocks, door trigger, and horn are at the body control unit above the gas pedal......just operate the car's power locks and you'll hear the unit clicking.

its the se-r with the immobilizer, and i was reading that i would would need to wire up my second ignition, does the 5901 have onboard relays for this or should i just go ahead and order some for this?

You also need another relay to wire up a second starter wire as well. You will need to buy additional relays to do that.
