Description

Bridge your gauges and modern engine management with one smart box. Zeus-Link™ reads CAN BUS data from Holley ECUs (Dominator, HP, Terminator X/Max, Sniper/Sniper 2) and GM OBDII ports to accurately drive Classic Instruments gauges—without a tangle of separate adapters. Connect up to six standard gauges and two auxiliary channels using any combination of sender inputs or none at all; if your ECU doesn’t output a value you want, you can still wire that gauge traditionally. The module includes warning and check-engine light outputs, a dash-light lead, and onboard diagnostic LEDs for power, BLE, and data status, plus a pass-through CAN port for additional devices. Setup and management are all handled in the companion app (App Store®/Google Play®): choose which gauges you’re running, assign inputs/outputs, view live values, and verify wiring. For maximum Holley compatibility on shared CAN harnesses, an additional resistor is available and Zeus-Link™ supports the extra Holley ECU connector when provided. It’s the cleanest, most flexible way to make your dash talk to your ECU.
