GM OBDII Port Compatible

Part Number: SN73Z-GM

Zeus-Link™ is an all-inclusive gauge interface unit that can connect to Holley ECU’s (Dominator, HP, Terminator X, Terminator X Max, Sniper and Sniper 2) and to GM OBDII ports, reading vehicle data from CAN BUS to drive any Classic Instruments gauges accurately. Additional pass-through CAN port connection for other CAN devices. Customers can connect up to 6 standard gauges and 2 auxiliary gauges using all sender inputs or none. All instruments can be driven traditionally if the vehicle ECU does not support an output the driver wants to monitor. Unit features warning and check engine light outputs, dash light connection and on-board diagnostic lights to give status of power, BLE, and data. For maximum compatibility with Holley products, there is an additional resistor available if there are other CAN devices on the same harness and the Holley harness has an additional Holley ECU connector for other devices. The entire unit is setup and managed through an app available on the App Store® or Google Play®. Configure which gauges are in the dash, how each gets its signal, view values being received by Zeus-Link™, and verify correct outputs and wiring all through the app.
