2018 Titan backup camera

[Rainman76]

Hey guys. I've been out of the install business for a while now, but I just installed an Alpine Halo9 in my 2018 Nissan Titan SV this past weekend. I didn't have the adapter for the backup camera at the time. It arrived yesterday. Bad thing is, it doesn't fit the harness in my truck. I did locate the camera wires in the harness. I also found the 6v power wire for the camera (blue wire). My problem is, there are 3 more wires. A blue/white, red and red/white. Does anyone know which is which? I do not know which are the signal wires or which one is ground. Any help would be appreciated. Thanks.
