The actual unit is the same as the 550-511. As far as where it connects, yes, you disconnect the touchscreen and connect your cable directly to the touchscreen connector ON THE EFI UNIT! then plug the other end to your USB and go to town with the Holley Desktop Software. **Q: Does anyone know what the holley end of the plug is called? can i buy just that plug and make my own cable? $60 for a usb cable seems a bit much.** A: I think it's a Mizu P25 Connector, however I wouldn't be surprised if the USB cable has some electronics inside the end to convert communications. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Buy it it works! *by J***. on September 13, 2025* Ls swapped mustang Holley terminator X Worked perfect bought a cheap one and basically threw away $40 BUY THIS ONE!!!!!
