Installed a budget cruise control system in my Z4 using the wealth of info available on this forum. The install was fairly involved given that I have a facelift car. Step 1 was to connect into the IVM, used the following guide to identify the correct pin hole;
Guys
Ive scoured this forum and cannot find a definitive answer to this
Which pin number on the DME do i connect the wire for my cruise control retrofit?
I have the n52 engine (3.0si) and everything else has been fitted.
The blue/black wire comming from the main harness is in the DME area and i have cut that to connect on the BLACK 6" cable as per instructions.
However, this is where the confusion comes in - is it pin 39 or 26??? Both sets of instructions say different things...
HELP!
Cheers

Then I soldered a long extension wire to take me through the network of pipes, through the bulkhead, then across to the driver's side, where I also removed the cowl under the steering wheel. I then implemented this suggestion to use an E39 steering wheel mounted cruise control module, hence the "budget" aspect. Z4 cruise control stalks are expensive!
With the price of the cruise control stalk going up a lot in recent years I decided to look into options to make our own cruise control stalks.
I was browsing the internet and found a forum where members with E46's have used the Z4 stalk on their cars when they have changed the steering wheel to a custom one.
So I thought, if the Z4 stalk works on an E46 then it'll work the other way. However the cruise on an E46, E39, X3 etc... looks like this:
A couple of wires need swapping round so I made up an extension lead and connected it up to...
I got the part below for £30 from a breaker on eBay;
Of the 4 wires coming out the back, 3 are useful according to this E46 forum;
If you want cruise Control without stuffing around trying to remove airbags or changing steering wheels, it is possible! Ive managed to get the cruise control retrofit modification to work on my 316ti with the cruise controlbuttons mounted on the dash. A little bit of background….. In Australia...

Wire B was connected to my long extension wire going to the IVM. Then began the scary process of splicing into the bundle of cables behind the headlight switch to obtain Ground (Wire A) and Power (Wire D). I used this YouTube video to help identify which wires to tap into;
I very gingerly sliced the insulation off these 2 wires;
Then started soldering;
Plugged into the module and cable tied everything up for its first test;
This isn't the final appearance; I need to tidy this up, connect it to a stalk etc. It works like a dream; long journeys are now infinitely more pleasant. It was absolutely worth the time, swearing and skinned knuckles.
