## Questions & Answers

**Q: How long is the cable.**
A: about 9 feet long

**Q: I would like to ask whether it is an ordinary signal line that does not contain any programs and protocols?**
A: Ordinary signal line although to use this line on a laptop to tune you’ll need to download the Holley tuning software

**Q: Does this work on a holley efi sne-550-511d and does this replace the existing cable to the touchscreen?**
A: It should work with your part number. 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.
