Mazda 323F GT

CRUISE CONTROL

Here I've tried to summarise what was done to install subj into 323F.

For now it's a basic explanation of what was done. Unfortunately there is no anything for 323F in production however I was surprised how close could be 626 and 323 sometimes. Unfortunately Mazda don't bother in using same wire colour codes not even on different models but even my 323F in reality didn't match a manual so had to think a lot of times before connecting (especially ground and +12V wires).

Parts that required:

1. Vacuum device with throttle cable and vacuum cable.

2. Main CC CPU unit

3. Main CC CPU unit power switch

4. Controls for CC - in my case it was a joystick

5. Throttle pedal.

There is a special contra-weight steel barrel attached to the upper end of the pedal to balance it and make it easier for Vacuum device to move the pedal.

What was done:

1. Pedal ramp had to be changed. Throttle pedal was replaced by 626 one with a lot of careful welding work.

2. Some mounts should be created for vacuum device to attach it inside the engine compartment. Also you will need to move few petrol pipes to free up space.

3. A new support mount was created for throttle cable because it's should be moved aside and due to different length (new pedal).

4. Vacuum device pedal cable attached to pedal.

5. Vacuum device attached to engine free vacuum socket

6. A Main CC CPU unit installed somewhere inside dashboard and connected to vacuum unit

7. Main CPU power switch installed and connected to CPU

8. Need to find the place where to install CC controls and connect it to CPU. I was not able to find better place than this one

9. There is one thing left. CPU also should be connected to the dashboard wires to receive data about current speed. There is a speed sensor on a dashboard which should be connected to CC CPU (shown on a pic connected by wire)..

Also there are two other connections to CC CPU unit:

1. To Clutch pedal sensor

2. To Brake pedal sensor

They are required to stop the system when you touch Clutch or Brake pedals. If you will push throtle it's OK and after you will release it (for example after overtaking) speed again returns to preset one.

This is electric diagram to show all connections:

PS: colour codes could be different for your car.

It's a bit old type system - it's moving not throttle but pedal itself which I found a bit funny. Also vacuum device producing a funny noise - sounds like somebody smacking so I am calling this Smacking Control system
