cruise control help!

Needs to be the right one of the two.

Think it changed at some point in time, can't remember details just now.

If you message me with your VIN I can look into it for you tomorrow.

T11a pin 10 for your car, built 31/03/2004. It ends up on pin 14 of the 81-way connector at the engine ECU, if you fancy taking a different way through.

 

Same T11a connection for any car built before May 2004 by the looks of it. T11b pin 6 from May 2004.

Thanks very much for that! Mega useful.    Although now back to changing the pins around 🤦🏼‍♂️

Team - bit of gen to summarise how I got mine working (probably obvious).

 

T11a pin 10 ONLY (for my pre may 2004 car)  

 

DONT try and piggy back or an ignition wire from the fuse box, this caused a P1689 code for me - use the brake T4d pedal plug, pin 2 as the wiring diagram says and it works!…. Obvious stuff I know.  

 

Ensure you cycle the ignition having activated it via the OBD.

 

  Very many thanks to Breezy_Pete for his time and wealth of knowledge.
