Hi all,
I’m trying to add basic functionality to the cruise control system on my car, which uses a Bosch EDC15P+ ECU (from a 1.9 TDI engine). Specifically, I want to:
1. Install a simple ON/OFF switch to enable/disable the cruise control.
2. Add a push button to set the desired speed.
I’ve read that the EDC15P+ ECU supports cruise control via specific pin connections, but I’m unclear on:
Which pins on the ECU are used for these inputs (ON/OFF and Set Speed).
Whether I need any resistors, relays, or additional components to safely wire these controls.
If anyone has a wiring diagram, pinout for the EDC15P+, or experience setting this up, I’d greatly appreciate your guidance!
Thanks in advance for your help!
