Cruise pilot aftermount

[goethfather]

Hello fellow audi owners ;)

I was woundering, is it possible to install a cruise pilot on my car, when it wasent born with it.
is it just plug and play ??

I found this cruise pilot online, and i'm not sure if i just can install it and it works, or i need something els to get it to work ?

it is from and 00, but was installed on an audi from 99. And mine is an 97 :)

I wouldn't be 100% sure the 2000 model control stalk would fit the wiring on your 97, a few things were different about the very early models of the B5.

Also adding cruise control isn't quite as simple as adding just the buttons, the entire system is run off vacuum so without all the network of piping, as well as the wiring harness and control module, you're not going to get very far sadly, probably not worth the hassle of trying to retrofit either. The system is rather poorly made on the B5 and is prone to failure

For adding cruise to a 97 B5, you first need to get all the pieces that go under the hood. The vacuum pump, the vacuum diaphragm, and the linkage to connect it. Once you have that, you finally need the Cruise Control Module. This is the computer that controls the vacuum pump.

The Module will need a few things: power, ground, and Vehicle Speed Signal. It will also need control switches. At a bare minimum, you need a SET switch and an ON/OFF switch. The rest are optional (Cancel, and Accel/Resume). It can work without those. Technically, it can work without the ON/OFF switch by hardwiring it ON, and using the pedals to turn off the cruise - but that removes a safety feature so I do not recommend it.

There are several redundant safety systems. You should connect and implement ALL of them. You will NEED to connect the ON circuit through the brake light switch (and clutch switch too, if manual). This is very important for your safety, so the cruise will automatically cancel if you hit either pedal. You also must connect the brake light signal to the module. In case the first switch sticks, the cruise will immediately cancel whenever the brake lights com eon. You should also route the vacuum line between the pump and diaphragm through the brake and clutch vacuum vent switches. This way the throttle cut is immediate if you hit either pedal. Again, important for your safety. If your car doesn't have the vent switches, you'll need to add those.

The circuits to hook it up are very simple. If you need specifics on how to connect the module, just ask. Using the OEM stalk switch is not required at all. You can use a regular toggle switch for the SET switch. Put it anywhere you want.

NOTE: I have never added cruise control to a B5. I have never seen a B5 that didn't have cruise control. I am not a mechanic. I merely studied the wiring diagrams to arrive with what I would consider to be a good understanding of how the system works. If you plan to install or modify a cruise control system, I advise that you do so with caution. I also advise that you study the diagrams yourself and be sure you fully understand what you are doing. Then watch the movie Runaway Car (1997), just so you have a firm grasp on what can go wrong and how important the safety bits are.

also it being a 97 will make it bat shit fucked to get the right parts. its kinda the bastard year of the a4. (In North America anyways)

^Respectfully, I don't think that's accurate. The cruise parts are the same for all the AEB's, 97-99.5. And really only the linkage rod, actuator and bracket have to come from the AEB. And if those are tricky, similar parts could be modified to work from other models (for example V6 cruise parts could be made to work). The vacuum pump is the same even for similar year A6 and A8's. These parts should be fairly easy to come up with. It's a very doable modification, and worth it for somebody who does a lot of highway driving

Wauw guys.. thank you so much! I'm really overwhelmed with these responses :) well it sounds like quiet some work, i think I'll wait.

Again, thank you so much, amazing that you want to help so much! :)
