Anyone know where the VSS wire is?
 

I have a 2000 E Class. Everyone keeps saying there is green/black wire in position one of the radio harness. But I don't have one. In block A of the radio harness I only have a gray, red/white, yellow/balck, blue/white and brown wire. Is the gray wire the VSS wire?

What do you need it for?

I need it for an Alpine navigation system. The system needs to know how fast the car is going in case it loses track of the satellites.

Maybe this will help?

Thanks for the diagram. I actually already have it and suspect that it is for the 1996-1999 W210 or maybe a different chassis altogether. I think they slightly changed it for the 2000-2002 W210. The A block which they show having 7 wires--my 2000 E320 only has 5 wires. I suspect the fiber optic system can send some of those signals that used to need a designated analog wire as my A block does not have an illumination signal at all.

My 2000 W210 E320 has:
1 empty
2 gray wire--have no idea what it does
3 black/yellow wire--have no idea what it does
4 red/white--constant 12V just like your diagram
5 blue/white--remote turn on lead just like your diagram
6 empy
7 empy
8 brown--ground wire just like your diagram

I drove around today with a volt meter attached to the gray wire and then to the black/yellow wire. No fluctuation in the voltage so I assume I can rule out either of those wires as being the VSS. So how did the stock radio get it's VSS signal? I suspect through the fiber optic connection. So that means I need to hunt elsewhere for the VSS signal wire which other people on this forum have said it is a black/green wire but no one has really given me a specific place where I can find it. Alpine suggest to put the car up on jack stands and tapping into the transmission wire harness but I don't really think that would be good idea. Somewhere in the car the fiber optic network must be getting a VSS signal. I just need to find that and tap into it also.

Thanks for your replies.

Fiber optic is only for teh CD changer.

I believe the fiber optic network does more than just the CD changer. It also carries phone signals, GPS info, connects the steering wheel functions, etc.

the grey wire goes straight into the diagnostic connector pin 33...the yellow/black wire will mute the radio as soon as you connect it to ground (telephone mute)...the green/black wire is no longer to be found in pin pos 1 since the 2000 modelupdate...you will have to get it out of the rightside cable gutter - near the A-pillar...green/black.

...ow...and the original headunit got it's VSS signal through CANBUS (brown and brown/red wire in C connector)...but that is of no good for any aftermarket HU.

greetingz,

Thanks Steve! I did my Nav and iPod controller install today. Pics are here:

I will like to change my Audio 10 to pioneer avic-x1bt navi system. I looking for the connexion diagram of audio10 and the wire diagram of ampli had in the car. I will like to use ampli from my car. do you know if the attach is the same to my system. Can you send me the diagram you used to install you hifi system? or another audio system diagram what you have?

Thanks for you help.
