Suspicious connectors

[Rouge5]

Hi all,
The last weekend I was cleaning the moonroof drains and found these 4 connectors in the left side of the trunk.
Do you know which is the usage of these connectors?
or why do the car have them?









Thank you!

I'd guess they are stereo component wires. Like, for a disc changer, satellite radio tuner, bluetooth control unit, or amplifier. If the car was older, I'd say power antenna as well. Of course the FSM will spell it out. Have you looked there?

[Rouge5]

But my car has all those features connected and working correctly (bluetooth, SAT radio, amplifier, cd changer)
let me check the FSM

[centralcoaster33]

Yeah, check that AV chapter. That's where I saw the satellite and blue tooth bits. Perhaps your car was on the fringe of a change in AV components and you have the wires, but the bits have been moved or combined in the front. I'm not sure what else would logically go back there. Window defrosters, heated rear seat control boxes, SRS control boxes, power reclining rear seats... I'm totally guessing and actually don't think it's any of those. The grey plugs remind me of factory amp wire connections, the white plug reminds me of speaker wire pairs, the blue plug reminds me of a head unit type connection but seems kind of weird. Again, totally guessing, but based upon personal experience with other Nissans.

My guess is "JDM stuff". I have seen some of those in the wiring within the dashboard of a fully loaded car with no room for anything else.

I found that 1 connector is for the rear camera, and other for the "rear wheel sensor", my car doesn't have any of those

[centralcoaster33]

Interesting. The FSM did say the satellite and blue tooth bits were back there. Did you see those pages? I know you said you had those features already, so I find that interesting also. That would cover at least 4 plugs I guess... I mean, all 4. Camera, Wheel, Satellite, Blue tooth.

Not on this brand but I've seen like heavy burglar or entry alarm stuff back there.

[Rouge5]

Yes I saw those pages, I'm really sure that the Bluetooth and satellital radio modules are connected haha, they are under the jack, months ago I removed them to clean them, and I reconnected them.

Maybe I need to remove the front console/radio to discover if there are the other side of this wiring haha

[centralcoaster33]

Shouldn't have to remove the front to see if they fit into the back. The wiring diagram should spell it out. If the wire colors match and the plugs are the same, then that's what they're for I figure. Kind of reminds me of an old TV episode, maybe I Love Lucy or Andy Griffith. The characters get their vehicle worked on at a middle-of-nowhere mechanics shop. When they go to get the car and pay, the mechanic shows them the car, hands over the keys and hands over the box. What's this? Oh, that's all the extra parts I found on your car! LoLz

[Rouge5]

hahaha


Look, these are the bluetooth (up) and satellite radio (down) modules, and his connectors, they are bigger than the connectors in the harness

[centralcoaster33]

Well, that kind of throws my theory off. And that was based upon the FSM. Now the FSM doesn't match?! That's not good imho. I'm tempted to go back to my initial guess of amplifier stuff, but maybe that's just habit.
The mystery continues?

Where'd you get those units? Friends car, junk yard?

[Rouge5]

Those units are from my car, they look damaged/bent (but working good) because the car had a crash in this side (rear left side), I bought the car with the savage title but it looks ok.

The amplifier is in the right side of the trunk, below the black foam too, and have another big connectors.

[centralcoaster33]

What year is your car according to the sticker in the door jam of the drivers side door?

[Rouge5]

My car doesn´t have that stickers, I think because it was repainted haha, but I know that my car is 2008

[centralcoaster33]

Okay, I was just curious. I know a 2008 in USA is a 2007 elsewhere. So, I was thinking I might look at the FSM for 2007 for some wire options.

[Rouge5]

But remember the "first generation" of altima coupe was in 2008
Also my altima was sold in Texas

[centralcoaster33]

Doh!
