need installation help!

[lkh5650]

hi i am trying the installation with my friend for the first time..and i am having a few problems right now.

i guess i will first start of stating the system i have.

2010 base model (sport)
axxess steering wheel control aswc-1
jvc kw-nsx600 headunit


first of all, the rear view camera wire that powers up the camera (red wire and black wire, i guess black is to the ground) is kind of short to reach the headunit. in this case, where should I connect it?

secondly, for axxess, it says
1) locate the correct swc wires in the vehicle's radio primary or secondary hardness as described in the vehicle information sheet found on the axxess website. connect the correct wire color from the aswc to the steering wheel control wire(s) in the vehicle?
2) also, it says if you are using newer jvc radio, plug the included female 3.5mm connect with the brown and brown/white wires into the male 3.5 mm connecter of the aswc-1 harness. connect the swc wire (normally blue/yellow) to the brown wire of the aswc-1, isolate brown/white wire and tape it.

so, in the JVC manual, it says blue with yellow stripe is the steering remote control wire, so all i have to do is connect with the brown wire that is with the female connecter? what do i do for 1)? i look at the application chart and for 370z base it says steering wheel control connector is 7552 shell and vehicles 1st swc wire color is dk blue.

what is the swc wire....? I am so confused and i need help..

Thank you
