Routing electrical wire from the engine compartment to the inside of the automobile


Recommended Posts

Greetings, everyone.
I need the capability to link my C-Tec charger to the battery of the new C-43 AMG coupe since I have a tendency to sometimes leave the vehicle inactive for a duration of 4 to 5 weeks.
I am aware that the battery is located in the engine compartment, and while I have the option to connect directly there, I am unable to do so since my vehicle is parked in a private community car park with other inhabitants, and it is not permissible for me to have a cable running across the shared areas. Due to limited space, I am required to reverse into my designated parking area. Therefore, driving headfirst into the slot for easy access to the front of the car is not feasible.
I have just sold my previous vehicle, the XKR Dynamic R, which had a battery located behind a panel at the back of the trunk area. To prevent the presence of cables that extend behind, I connected a cigar lighter socket (equipped with a fuse) in the trunk directly to the battery terminals. This allows me to connect a charger without the need for cables running across the floor.

I want to replicate this process on the C-43, however it will be necessary for me to thread the compact charging wires through the engine bulkhead, starting at the battery terminals and then routing them under the carpets, ultimately leading to the trunk area. I really dislike visible cables, which is why I want to hide them behind rugs or trim.

I have been informed that the current cigar lighter will deactivate when the ignition is turned off, but I would rather have a direct connection to the battery.

Has anybody encountered the process of routing a cable through the engine bulkhead? I am certain that there are existing grommets that facilitate the passage of cables from the engine compartment to the car's interior, but I have not personally seen them yet. I have seen the presence of a fuse box located under the floor of the vehicle's trunk. Is this the optimal course of action?

I have had this new automobile for a little over two weeks now and have travelled around 450 miles. I have a strong affinity for it, nevertheless, I am still perplexed by the means by which the majority of the menus and settings may be accessible.
Perusing the comprehensive manual reveals other features that I assume my vehicle lacks, thus adding to the confusion.

Any advice or ideas would be much beneficial.

Please include information on the power source you intend to use for operating the charger.Yes, a 240 volt power source is required.However, you claim that you are unable to run wires down the floor.Does the wall have a 240v socket? If it does, then this will provide the answer to my query. Furthermore, may I inquire about the specific year of manufacture of your Mercedes? What is the C43 AMG?

I appreciate your prompt reply.

There is a conventional 240-volt electrical outlet mounted on the wall in the shared garage. The issue at hand is not related to that.

I just acquired a brand new automobile, which was previously used as a demonstration model. I took possession of it three weeks ago.
I would want to ensure that if I were to drive directly into my designated parking area, I would be able to effortlessly connect the charger to the main power supply and extend the charging line to the engine compartment. Due to limited room for manoeuvring, I often reverse my automobile into the parking place. Next, in order to route the charging wires into the engine area, they would extend the whole length of the vehicle down the floor, perhaps causing issues for cars parked next to mine.

To prevent my neighbour from accidentally stumbling over my charging line when entering his vehicle, I am endeavouring to establish a battery connection in the trunk that will be in close proximity to both the power socket and the charger.

Apologies if that seems intricate.

Is the automobile covert?
Is it possible to lengthen the 12-volt output from the charger and route the wires via a floor cable cover? The only need is to connect a short cable to the battery located under the hood. Simply attach a push-in connection to both ends of the charging cord and connect the charger whenever necessary.
The cable cover may be conveniently positioned under the middle of the automobile, ensuring it remains unobtrusive.
It would be far more convenient than the process of threading cables through the bulkhead and carpeting of a newly manufactured vehicle.

Is it possible to avoid running the lines on the floor below the car? This would eliminate the risk of tripping hazards. I am required to do this task inside my driveway since I am unable to exit if I drive ahead.

In the past, I had an XK and had my CTEK hooked in the trunk, similar to yours. I used a CTEK 56-531 extension cable to establish a connection between the battery terminals, resembling a socket.

For my Mercedes, I attach the CTEK charger to the battery located under the hood. I then run the wire through the windscreen and over the side mirror, allowing it to reach the rear of the vehicle. Amazon offers a 2.5m extension cord that may be used to extend the reach of the connection to the charger.

Wouldn't he still need to open the car's hood each time and manipulate the charging wire to connect it to the battery terminals?
For what it's worth, I see the advantages of a setup where one just opens the trunk, connects a cable, and then closes the trunk, particularly if this process is going to be performed often.

It is likely that if there is a fuseboard in the boot, there will be an unswitched supply cable located inside it. Performing a little experiment with a multimeter can quickly determine if that is the situation. If such is the case, I would anticipate that connecting your charger to a fused outlet via piggybacking would be rather simple.

Furthermore, to be honest, the Jaguar vehicle would deplete the battery within a span of two weeks and result in many complications. I disliked leaving it at the airport while going on vacations.
The battery of my Mercedes retains its charge more effectively.

With my last Mercedes, I used to connect my CTEK charger to the compact 'start-stop' battery, which was situated in the trunk under the carpet. This ensured that the battery remained fully charged during periods of inactivity. You may check whether there is an existing attachment point in the trunk for the CTEK.

Alternatively, consider purchasing a USB jump pack if you plan on leaving your vehicle alone for extended periods of time.

Consult a reputable auto electric shop to install a secure mechanism for charging the batteries.Remember to not overlook the warranty on your automobile. Contemplating electric vehicles only within a limited scope
