hi, im in the process of takin a cruise control kit off another e30 to fit onto mine, was wondering where the control box (ecu) is located for the cruise control as ive heard this is needed, also what exactly is required to get it up and running into my car.
thanks

You need the cruise control ECU located under the dash (passenger side) next to the engine ECU, you need the cluch sensor and cluch sensor suport, you will need the cruise control servoengine with the bowden wire located next to the air filter hose, your will need complete wire harness (from servo to cluth and brake pedal, to cruise control ECU, to gauges, and to cruise control stuck) you will also need the gauges adaptor for the connectorand finally the cruise control stuck.
If the cruise control ECU comes from a Diesel engine, previous info is not valid, and this cruise control will only fit for diesel engines.
Pre and Post models are fitted with different cruise control stucks. Pre (4 wire connector) could fit also post models steering column. Post (5 wire connector) cannot fit pre models steering column although both stucks can fit any cruise control ECU.
Good luck go on seems difficult but not so much.
Sorry for my english

On right hand drive e30's the cruise ecu is behind the black plastic cover inside the glovebox.
You'll ideally need:
Ecu and bracket
Servo and cable
Wiring loom
Clutch switch and bracket (unless it's auto)
Cruise stalk
Steering column lower cover (has a cutout for the extra stalk)
There is also a green plastic adapter attached to the rear of the instrument cluster, it slides downwards out of the cluster and provides the speed signal to the cruise ECU.

I fitted my cruise control last weekend. The “brainâ€a is above the ECU to the right of the steering wheel in a RHD car. Also above the ECU is a black plastic relay box for the immobiliser part of the OBC; get the right one the CC brain is a silver box. You don't really need the bracket; it didn't fit my car.
If you car is pre-1988 (and the donor car is too) you'll need the connector thing to go on the back of the cluster. Not for post 1988 cars.
The clutch switch and related bracket differ over the years and the one you pull might not fit. They're actually cheap to buy from the $tealers and available (pair together under £10).
When you pull the actuator motor be careful not to break the plastic clip on the throttle lever arm. Don't flex the plastic much when you take it out; they get brittle with age. Also be sure to get the rubber gasket for the bulkhead. Silicon spray helps you get it out and back into the new car without tearing it.
You also need the screw which holds the CC stalk on and goes through the wiper stalk or you'll have to buy another one. Your new car won't have the right size.
Make sure you install the brain box with the terminal facing to the left otherwise the loom is too short.
If you haven't got downloaded all the articles on this subject (and there are several, some with good pictures) I have them in a convenient folder and will email it all to you if you PM me with an email address.
