I don't think soldering would be necessary. If you look at the pictures where the faceplate is removed, you can clearly see that the front USB port is connected to the PCB through a flat ribbon cable and a connector. I think you might be able to just disconnect it and run a different USB cable out the back, if you figure out what type of connector you should use to connect it to the PCB.

VICTORY

Pin 6, directly applied 12v
did not use the reverse wire on the RCA loom (didn't work)

took Green wire from other connector i had coming in from Ali
stuffed that one in the pin 6
Add 12 volt



note camera not in bumper yet, this is just wiring test for PCCM
want different camera that installs from top of the flat area over the license plate, not vertical install through bumper via big hole

now to test if i can rig up the USB in the back as well, to confirm what others said i have no doubts that will work as well)

medicus

Good job but does this workaround only apply to manual Or also for Tipptronic?

svandamme

how would PCCM know the difference?? its 12v to pin 6
theres no manual or tip story here

Its not even a Porsche story, with this info, you can install PCCM in a Honda and get the reverse cam to work

Alternodor

Sorry, so many questions.
So Pin 6 to 12v. What about Pin 8, still connected to rear reverse light? If not, how does the PCCM know to change input to the camera?
Also, where did you get the 12 V for Pin 6?

svandamme

Updated the install guide, clarified step 4 and 6 to make it less "ambigious"

And added camera diagram

little scare, suddenly my USB drive front no longer worked
And FM was up the wazoo
thought i had fried something in my testing, but a PCCM+ factory reset cleared it up. except for the USB drive.. but since Android auto works, the usb port works, I think the USB drive itself went bad

myw

It would work for both as it’s the 2ndary reverse trigger

but for the triptronic cars the reverse mode is already flipped via the canBus - primary reverse trigger

medicus

Thank you, thank you, thank you. That's exactly what I mean. Maybe you can explain this again to @svandamme so that he understands it.

svandamme

there is nothing to understand, Like I said, it works regardless of what car you have, even works on a Honda if you are so inclined.

MYW only confirmed what I already told you

svandamme

I manually applied 12 volt from the car to pin 6
this was just a test to confirm it is pin 6

For a real install, you will need to get a switched 12 volt off your reversing lights...

There is no pin 8, its a 6 pin connector

medicus

I just wanted to know that because we have repeatedly seen pictures in the thread of members who had a picture on the display using an av signal after they had taken the reverse gear. But no one wrote anything that they laid any cables on the wiring harness.

Great to hear looks like what myw was saying is holding true (put power to pin 6). However there is a pin 8 - pin 8 is the pin right next to pin 6.

If you put a multimeter on pin 8 with no power going to pin 6, it should be showing 0 volts. However if you put power to pin 6, do you now see voltage on pin 8? If so, you could then power the camera off pin 8. This is what myw has been saying may be the case here.

Alternodor

ON post #1145 there is a pin 8. Are we using the same pin numbers or a different set?

#1145

svandamme

I didn't measure anything, its back in the car now.
I found it confusing to talk about 8 pins on a 6 pin connector...

I don't really see much benefit in using power off the PCCM because than you gotta snake an extra wire from the PCCM all the way to the back of the car..
Surely there are other sources of 12 volt to the rear of the car?? hell you could even get it off the engine back if you want and it would be easier than snaking the wire all the way from PCCM to the back??


In tryin the USB back port (with wrong cable) it does appear I fried my USB stick, very odd, it still works in computer, but PCCM won't read it no more.
formatting did not help, stick is dead to PCCM but works everywhere else...
new stick works in PCCM..

svandamme

Considering you need to get reverse 12 volt from the rear lights
the most obvious solution to me would be to use that to power the camera..
(There is no way that tiny camera is going to kill the lighting circuit, it draws very little power)

So as long as you get 12volt at the lighting from the 12 volt and not the ground wire, it should work just fine
(ground pole is no bueno A might get some amps from the bulb over to the PCCM if the ground for some reason goes bad B if bulb blows camera would die)

If that works, there really is no need for that pin 8 or to snake 4 meters of wire from PCCM to the camera
