Hey crew,

I purchased a set of Benz paddles in attempt to retrofit to my CTT per the couple writeups on the forums. No avail.

There was a good write up from the non Multiwheel from the cayman which had SIMILAR wiring to tap into... although it was mentioned some models needed resistors etc.

The paddles I purchase had two leads from each paddle that were the same color (green) for both wires, not the black and blue/yellow from others shots. Additionally, my wiring harness within the wheel includes black, grey, brown, yellow,white, red. A voltmeter showed 12 VDC on the grey.

I tried using using the attached schematics, thinking that my two green wires of the paddle were a ground, and blue/yellow per the diagram. I attached one green to the black and the other to the white (upshift) and one to black and the other to red for downshift.

Result: nada. Even with reversing the green wires (not knowing which was “black”/ground”.

Anyone have insight on this on the 955 wheel?

TIA.

 

When you say on the forums, do you mean the Cayenne 2004-2010 forums or others? There are writeups for the 955/957 here in the Cayenne forums. Several members here have done the conversion and I actually have a set of shifters sitting in a box waiting to be installed when I have a moment. When I have a chance, I will try to find the link to the 955/957 writeup if you don't beat me to it.

 

I’ve searched a decent amount. If you find anything more conclusive please let me know!

 

As it turns out, the thread that I was thinking of was the Cayenne thread with the Boxter-related DIY at the end. I will dig deeper if I can... Here's the thread https://rennlist.com/forums/cayenne-...-shifters.html

 

My paddles - still not yet installed LOL - have black and yellow wires on one and black and blue wires on the other.

 

I'd reach out to user Bosty who posted the thread I referenced above. He should have some thoughts to help out.

 

Putting paddle shifters on a Tiptronic auto trans seems a lot like lipstick on a pig. Paddles won't make the transmission respond any more quickly.

 

I dont think it is as simple as you are trying to make it. I believe, and I definitely might be wrong, that the shifters in the oem steering wheel talk to the PCB inside the bottom of the steering wheel, which converts the command into a CANBUS command which is then sent to the trans computer. Again, I could be wrong. I went the below route on my CTT 955. If you want to tie in a 2 wire switch, you can attach to exactly where the microswitch is in the steering wheel. If you are replacing the steering wheel you will need to create a pull up/ground bypass circuit. Also know that BOTH sides need to be connected on that PCB.

 

 

If course not, just makes it easier to drive than the silly thumb buttons so you'd run it in manual mode more often.

 

Those thumb buttons are ridiculous. I guess they work in a straight line when overtaking or something like that but they are completely useless when turning the steering wheel.

 

Exactly why I put a paddle-wheel on my Boxster with PDK. Haven't bothered on the CTT - if I want to have fun driving - it's in the Boxster.
