Holley | Digital Dash I/O Adapter w/Unterminated Vehicle Harness

Holley – Digital Dash I/O Adapter

Description

The Holley Digital Dash I/O Adapter (p/n 558-433) adds 10 more inputs and outputs to your Holley Digital Dash. Unlike the 558-434 model, this version includes an unterminated vehicle harness, providing greater flexibility for custom or specialized wiring configurations. All connections route through a single 26-pin connector. A USB flash drive preloaded with the required dash firmware update is included. This is the ideal choice for builders who need full control over wire routing and termination in their EFI builds.
