2010 nissan maxima, gps tracking device

I need the wiring or electrical diagram for my 2010 nissan maxima. I want to install a GPS tracking device that has three wires, red(constant source), black(ground) and white(accessory) and can't find where to connect the white wire. Any help will be greatly appreciated.

I hope you can help, I am installing a GPS tracking device in my 2010 Nissan Maxima and have a question about one of the wires. The red goes in constant 12volt connection, the black is ground and the white says ignition wire. Does that refer to an accessory wire, a source that is on when the ignition switch is on? Thanks in advance!

I need help connecting the wires on this GPS devices. It has 4 wires, a red that connects to a constant source, a black to ground, a blue for a relay which I don't need and the most confusing one, a white wire. The instructions refer to this wire as the ignition event wire. It says to look for the wire in the steering column. Isn't this wire the accessory wire? How and where can I connect this wire? This is the only wire preventing me from installing it.Thanks in advance
