Front and rear dashcam preparation option

[fastlorenzo]

In I came across the following pinout someone did for the front connector. It came from this thread on a 911 forum.

Thanks, I found that one as well but I want to double check first as I see 6 cables in the connector on the Taycan and the 911 schema only has 3 listed.

I went with a FitCamX. Plug and play 20 minute job.

I've see that one as well, really tempting but I believe it doesn't have a Starvis2 sensor or a rear camera (could you confirm this?).

FitCamX does have an available HD rear camera, but the sensor is a GC4653, not a STARVIS 2.

I think your theory about the other 3 being just a connection to the back is a good one, but needs confirmation.

I think your theory about the other 3 being just a connection to the back is a good one, but needs confirmation.

I tried the installation today for powering the dahscam with the pre-wired connector.
I can confirm 3 of the wires are running to the back, the 3 others should be Always-on 12V, Ignition 12V and ground.
However, the always-on wire doesn't have any power on it. After reviewing the "Installation and Conversion Instructions" from NHTSA (https://static.nhtsa.gov/odi/tsbs/2023/MC-10232387-0001.pdf), it looks like I need to add a fuse somewhere, probably the one used for always-on 12V:

The issue I have now is the document mentions right fuse box, fuse holder SF1, slot F2. I'm not sure though which exact fuse it is as the fuse box is labeled by rows (A, B or C) in the Taycan manual.
On the passenger side, row A fuse 2 isn't labeled in the manual, so I believe it could be that one but I'll have to check it.
Regarding the rear camera wiring, I decided to run the Viofo cable through the back (bottom right side of the car); that went smoothly and I believe will avoid me impedance headaches )
I've ordered some other Fakra / MMCX connectors though, so if I find time and motivation I'll still try to make it work with the pre-wiring, but for not it works with the official Viofo cable.

For information, this is the fuse mapping I made from the manual; the grayed out lines are the ones with empty fuses:

And here is the picture of the pin-out of the front connector:

It should be a quick job to ring through (using an Ohm meter for example) which missing fuse is feeding the pre-wire.

Did you by any chance figure out which fuse is used for the switched 12V?

Always good to know the fuses which feed anything you're adding to the car.

I've found the 2 fuse holders that are pre-wired:
- Always-on 12V is located in passenger side, fuse A2
- Ignition 12V is on the driver side, fuse C8 (Interior mirror from the manual)

I think I'll check to use another ignition 12V fuse on the passenger side and use a fuse tap. The provided hardwire kit from Viofo has really long cable and a voltage drop check box, I don't think I'll have enough room to put it behind the overhead console.
I'm planning to use the Passenger A2 fuse holder for the always-on 12V and maybe the Passenger (Top Right) A1 fuse holder (Smartphone tray) for the ignition one

 

[fastlorenzo]

I've finally finished, I used a fuse tap on one of the empty fuse slot for the ignition 12V (Passenger (Right) C3 - Brake booster control unit (RHD)) and another fuse tap on the pre-wired always on 12V (Passenger (Right) A2)

Happy to help by providing further information to whoever needs it

I posted an illustrated guide to using the dashcam prewire option including things I learned about it at this thread and from additional experiments:
