@Chris.ac

Do you have an image of the throttle body and control/actuator. Im having a look at adding it to ours.

I'm looking to add cruise to my 2003 3.0.

I know it has been done before using an Rx300 actuator with cable, auris or similar 4 pin brake switch, previa cc ECU and control arm.  I have wiring diagrams etc.

 

I have checked and I have the correct plug under the bonnet, I have the 4 pin wiring for the brake switch but I can't find the plug for the ECU.. I thought it may be behind the coin holder thing under the door switches but I can't see it.  Now looks like it could be under dash behind stereo near glovebox. 

 

Does anyone know for definite where the cc ECU is so I can chase the plug down please?!

 

Thanks

Hi Alex,

 

Bit out of my depth here, but ...

 

I think the assembly behind the front bumper is the distance / radar control.

I also believe it is very expensive to retro fitif at all possible on the early Gen 1.

 

I also believe that the 'simple  cruise control. can be retrofitted to the Gen 1 facelift, but not the prior model.

 

Unless you are considering changing the manual throttle body for the fly by wire version !

I have no idea what is involved installing that update.

 

Good Luck.

What about the simple cruise control?

Chris.ac is very knowledgeable on this subject (among many other subjects).

 

I believe that in order to work the cruise control system needs to actuate the throttle electrically.

The early Gen 1 vehicles do not have an electrically operated throttle body.

Whether an electrically operated one can be retro fitted is beyond my knowledge.

 

Send Chris a PM if he doesn't respond to this thread.

 

The simple cruise control, by my definition, simply tries to maintain the set speed.

The complex system, uses RADAR to maintain the above AND a given distance to the vehicle in front.

The simple system is not linked to the braking system, the complex system is

 

I apologise if you already know all this !
