Where to take the reverse signal?

[kang]

Hello Guys,

May I kindly ask for your help?

I need to find a way to take the reverse signal on my FX45 2003.
I tried to find the signal on all the plug inside the centre of the car. Every positions on the plugs who go to the radio, air-con, ... and also under the shift panel.
Unfortunately, I cannot find a way to have only the reverse signal :-(

I also check the wiring schema that we can find here:
http://x.infinitihelp.com/forum/local_links.php?catid=9#.UX0bQLU9F8E

I don't want to install a cable from the back of the car to the front.
The next step will be to find the plug: Back-Up Lamp Relay (B44) or the Transmission Control Module (F44) or the Display Control Unit (M75 terminal 8) or in the plug from the Audio Unit (M58 terminal 6) or in the A/C and AV Switch (M64 terminal 1)
On my car, I don't have any Display Control Unit, only a Display Unit (Orange screen) and no signal on the M58 terminal 6 nor on M64 terminal 1 related to the reverse.

Could you please help me to find the B44 or F44 plugs?
Could you please help me to find the reverse signal?

Thanks for your help.
I'm stuck with this signal around 6 hours now ;-(

your post is a little confusing, not sure if your looking to relplace the back up light bulbs located in the hatch or locate the fuse, back up camera wiring, ect... Please clarify and I'm sure someone would be happy to give some input remedy your situation.

Thanks Slamming45, I'll try to get more in details:

I'm actually finding a way to have the reverse (back-up) signal (12V) from the front of the car to connect it to the Alpine for the rear camera. Ideally, I would like to find it as close as I can from the radio.

So I figured it out from the back on the connector B81 (in the hole located inside the left of the trunk):


Then I searched on the B5 connector (under the steering wheel fully up), but I cannot have only the reverse signal:


The next step was to search in the F49 connector near the battery, no way to have it:


Should I take this signal from the back on the B44 relay (Back-Up Lamp Relay) or should I take it from the E19 connector located on the back from the glove box?
On the scheme that I found here (PG.pdf) I'm not able to see where is exactly the E19 connector.
As I can read, I should use the terminal 4 who is ORange on side F49 and Green on side E19.

Your help will be really appreciate.
I loose almost 10 to 12 hours for this connection :-(


By the way, thanks to the NicoClub to share all the details for our Infiniti

Finally, I take the signal directly from the Back-Up Lamp Relay (B44 - terminal 5 - LightGreen) located in the left part of the trunk:


Thanks to Slamming45 and to Zebra555 for the help

Now we continue with the project
