Retrofitting original sport chrono clock

[alex_bell]

HI! I just joined the Taycan community today!! I actually was looking to do this purely out of aesthetics where I wouldn't even wire it for now until a later date I will have the time and courage to wire it. Is just replacing it, nonworking, purely popping the top vent dashboard plastic piece of and popping this in?

yes, just remove old and install new cover and clock

interesting? Why was that?

I think it ruins the looks of the nice clean dash. It doesn't do anything useful for me and it sticks out like a pimple in my vision while driving.

Great right up, thanks. I’m having trouble with the connector on the back of the clock. I cannot get it to off. Any trick to it?

Hello Alex!
Thank you very much for this tutorial

Just to get it right: Which Pins (clock side; I think in your case the red / white / brown wire) have to be connected to pin17 / +[pin 31?] / -[pin30?] ? I already ordered the mentionted connector.

Thanks in advance!

Yes, this is correct, pin 17 for lin bus, 31 and 30 are for + and -

Use multimeter to check if 31 and 30 receives power, just to be sure

Thank you very much - but which PINs are to corresponding ones on the clock side?

In your first picture in this post, equals

red = LIN
white = +
brown -

?

Thanks!!

Instead of wiring colors(they might be differenr for you) - find terminal 30 and 31 measure with multimeter if there's 12v(make sure car turned on)

on clock connector - see pic in first post what is what

Hey folks. This weekends decided to retrofit sport chrono clock because my car came without it(and no sport chrono). I have that clock in my Panamera, so felt like something it missing, so here's short breakdown how I did it.

I bought used clock with backplate from local salvage yard for about $500, but I saw them also selling on eBay. I also made small wiring loom for 3 wires - Pos/Neg and LIN bus. You can use this PN 1C0973119B to get correct connector which will connect into clock, on eBay there are already with pins inside, or just add pins yourself.
Here's pinout of connector and how it looks

TO start I had to remove instrument cluster. To remove it you need to pop off plastic cover thats over IC and then unscrew 4 T20(or T25 dont remember) screws. Then IC simply pops off. Make sure car went to sleep so the screen isnt on anymore to prevent any damage when you disconnect it(it can take 5 mins to fully fall asleep sleep). Remove big connector first and then video signal

Remove video cable and big connector. Now we need to wire our clock to this connector. At first - remove housing, that purple small clip that holds connector in housing, just push it up and it will pop off. Next step - we need to add pin #17. This is where one of LIN bus wires lives and this bus made specifically to feed data to clock. The connector has 4 labels marking position of pins. The pin for #17 located in corner, but in my case connector didnt have pin, so I had to add one. You can use crimping tool to make it, but I didnt have this small pins, so I just found old wiring loom from VW and pulled one of pins from that loom and it fit perfectly

Next step - remove central speaker cover. Just use pry tool and pry it up. Remove speaker for some time, so it'd be easier to work.

At first I routed wires through hole near air vent channel, but I didnt like that I could see it when I'd put speaker cover back, so I drilled tiny hole behind air vent like 5mm diameter and routed wires there. Took a bit of back and forth, few wires to get it in a route I wanted, but eventually got it done

Last step - add power and ground. You can use any red wire on connector for +12v and any brown wire for ground. In my case I used PIN 31 for +12v and pin 30 for ground. Simply cut isolation off, soldered and put isolation tape back.

Now it's basically done. I insulated with same isolation tape as rest of the loom, so in my case it looks like its been factory made. Connect clock, connect instrument cluster(video signal first, then big connector) and turn car on. You should have your time reset, so go to PCM and set it again. The clock should synchronize with car time right away.

Basic clock feature does not need any coding and works right after connecting. In my case it worked right away. Clock arrow works well, backlight also works well(the one that lights up numbers). If you wan it to be a timer, you will need to code it to car, but I'll do that sometime later when I find reasonable priced steering wheel with mode selector and add full Chrono sport to car.

This is how it looks now

I hope it will help someone to retrofit it too. It took me about 3-4 hours in total with few coffee breaks.

Recently I also replaced CCS1 to CCS2 ports, so if anyone is interested - I can write brief explanation what needs for that


PS: Apologize for any mistakes or typos, I'm not native English speaker, but tried my best

That’s amazing! By the way, if the charging port is changed from CCS1 to CCS2, does it also require re-coding (PIWIS)?

Yes, you need to code both, HV charger and AC charger(2 modules)

did you also modify the AC Type-1 port (J1772) to Type-2 port?

 

[alex_bell]

Yes, I got both ports at once, but I don't think they will work, since other port also has AC/DC charger capability, so either AC/DC will not work with AC, or other AC port will not work. Best to change both

Exactly the same as the original design logic — AC and DC cannot be used at the same time. Looking forward to your next post! Because I also want to help make CCS1 and Type-2 the global mainstream standards!!

Im afraid that will never happen, both type1 and type2 are widely used nowadays

same story as miles vs kms, except its easier to switch miles to kms than type-1 to type-2

Hey

Does anyone know which VW pins I need to add them to the big connector? My connector hasn't got the needed Pins

Thank You very much!

I got a 32 pin connector with 32 pins of the correct type included from aliexpress for 2 euro
I screwed up 3-4 pins before I got it right so was happy to have extras, but that might just be me and/or the crappy crimp-tool I used
