Yes that is what I got, all you are interested in is the plug which goes into the clock.
You can cut the rest off so that you are left with 4x wires. Then you just tap those wires in to the existing harness.
Very easy install, I did not cut the original harness, just use some wire taps. (the clip type).

Hi Don,
Thanks for the link but it does not work...
Try to PM me the email contact you have please :cheers:

Roders,
You mean that the highlighted part number on the PET for the wiring harness for the chrono on Cayman 981 will work on Cayenne for the compass ?
Is that the one you've ordered ?

Thanks.

Here are pics of the harness. Have not had time for the install yet.

Termite,
Can you confirm the part number you've ordered from Porsche ?
I've just ordered 981.612.692.00

Hi Guys,

All you are really interested in is the plug end which goes into the clock and the 4-wires coming from that.
You can cut off the rest as you just need to wire tap them into the cables behind your PCM.

Are they the same colors ? Easy to find ?

Yes very easy.
Match the colours, there are 4 wires only.
12V+ (power)
Ground
CAN High
CAN Low

Connect them with wire taps and you are done :)

Ok, will have the harness tomorrow and will update here soon.
Thanks guys.

I think a bit more cable may be needed to connect them up. The cable I got was around 30-32" in length. It is JUST long enough to get my hand behind the clock and connect or disconnect it after running the wires down to the PCM.

As far as connecting it - PLEASE use Positaps. You want 18-22 size ones. The old blue "Scotch Loc" connectors destroy the wires you're tapping into. They're absolutely awful to use on any motor vehicle. Positaps cost more - but are much gentler on the wiring.

And I'm curious about the actual clock connector shown. There doesn't seem to be a recess with the female receivers/connectors in them. Is there a cover over the end?

BTW - @roders - have you done this job on a Cayenne? I see you primarily post on a GT4..

Hello Guys,
Just to say thanks for your help. I installed succesfully the compass to my dashboard with the Porsche harness.
The only issue I had is that I needed coding with PIWIS tester to activate the compass.
All went fine at the end.

Thanks again.

Glad to hear it worked for you. I may have activated my clock with my iCarScan - which can do some level of coding. Did you happen to take any photos of connecting up the wire behind the PCM?

Honestly no, I did not though of making photos but it is really intuitive, just to follow the colors from the original wire from the PCM.
The only real issue in the lenght from the Porsche wire which is too short. I had to make them longer to plug it to the compass.

Exactly what I thought might be a problem with the Porsche wire. The Chinese one is just long enough. Another 2" would have been nice - but not necessary.

Chinese one disapeared from the market...
