Technical Ducato 230 speed sensor location (automatic gearbox)

[Combonaut]

Hi, to install Zemco cruise control i need to connect the bleu speed sensor cable to the car wiring loom. Manual states location below fuel filter bleu wire comming from speed sensor on the gearbox. On a automatic transmission (4HP20) there is no speed sensor on the outside of the gearbox. wiring diagram of gearbox control i can not find . I guess the gearbox control unit also needs this signal so i can get the signal from that. Any help would be greatly appriciated.

update , found a Xantia manual on the transmission, speed sensor is located inside transmission and connected to ECU ( see attachments)
still no idea where to connect my blue wire...

Hello,

Why not contact Zemco and ask them? And confirm first of all the system is compatible with automatic gearbox. Is it an automatic? or some robotized manual like in newer models (x250, x90 until 2020)?
