-15% Holley Digital Dash I/O Adapter 7-inch Dash

Holley's 7-inch digital dashes are so awesome it is hard to believe that they can be made even more capable.

Believe it!

This digital dash I/O Adapter allows you to add up to 10 inputs or outputs to your 7-inch digital display.  The inputs can be monitored or datalogged on the display itself* just like the parameters that are provided from the ECU of the attached Holley EFI System.  The outputs can be used to drive a broad range of accessories when coupled with appropriate relays, drivers, etc.  On-screen digital switches can be implemented that send their outputs via this useful I/O Adapter.*

The Holley Digital Dash I/O Adapter is available as follows:

  • PN 558-432, Digital Dash Adapter w/o Vehicle Harness
  • PN 558-433, Digital Dash Adapter with Unterminated I/O Harness
  • PN 558-434, Digital Dash Adapter with Terminated I/O Harness

*When used with the Sniper EFI System the 7-inch display does not provide datalogging or on-screen digital switching capabilities at the time of this writing.
