Strange wires behind the bumper

[wgalagassijr]

Hi,

During PPF installation on frontal bumper (right side) we found this 2 disconnected wires. Any idea what future use they might have?

The wires are acessible without removing the bumper using the existing small “door” present on the bumper.

My MME is a 2023 GTPE and i live in Brazil.

Regards,
Wilson

Those allow you to power the 12V battery when it is dead. Otherwise, you would have no way to charge the 12V battery if it dies ( it is locked underneath the frunk lid which requires 12V power to open)

Great.

Thank you for the clarification.

Correct. See p307-8 of the 2023 manual.

I think those only allow you to pop open the frunk in case you 12v battery goes dead. The frunk is the only way to access that battery. Once in the frunk you would have to take some panels off to get to the battery. I think there are a few videos on youtube of people doing this.

As the video point out, the wires in the bumper only work to unlock the Frunk. To actually charge the 12 volt battery, you have to remove the panels and hook up a charger to the proper points.

Any recommendation about a good jump start model?

Where are you going to keep it?

Rick is correct, if the 12V battery is dead you won't be able to get into the car to retrieve a jumper box.

Great. Didn’t realized that until now ????

while 12v battery issues are much less frequent now you could go old school for only a few bucks:

Looks like you've gotten plenty of good answers, the only other thing is, if you use a high pressure car wash the cover will pop open!

Your are right. This community is really great.
Thank you all.

I got all my kids one of those car jumper batteries for Christmas one year. Also one for me. Many do and all people should have one in their car. If someone asks for a jump you can lend them the battery. I don't want anyone hooking up my car to theirs.
