Hey,

I'm trying to test a theory about cruise control and the older modules. See my thread: http://www.peachparts.com/shopforum/tech-help/313824-how-cruise-control-amp-repair-14-pin.html#post2895902

I was wondering if any of you might take a look at your cruise control modules and tell me if it has a coding plug on it. Your cruise control amp is located at the passenger's foot well behind the plastic panel.

It contains 4-5 resistors that tell the cruise control unit what quantity of impulses per kilometer to expect from the hall-effect sensor.

Its the black piece on the back of the unit.


If your willing, I'd like to see a picture of these resistors, so I can modify one of my plugs to the same values and try my theory out. A new plug is $40!

The plug is easily taken apart, just pry it out of the back casing, then release the clips in the center with a small screw driver. Finally tilt the plastic insert and remove it from the pins, you'll end up with this:

Here is the Manuel to check your resistor plug.
If you have a plug from a other model, is easy to replace the resistors and your done for 50 cents.

I believe a 2.2D should have plug number: 005 545 11 32 // 005 545 42 32
