Classic Instruments SN73Z-S1 - Zeus-Link Gauge Interface Module

Classic Instruments SN73Z-S1 - Zeus-Link Gauge Interface Module

Gauge Interface - Zeus-Link - Speedometer / Tachometer / Fuel / Oil / Voltmeter / Temperature / Auxiliary - OBDII - Holley Sniper - Each

Compatible with Holley Dominator/HP/Sniper/Terminator/Terminator X ECUs

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.

• Warning and check engine light outputs on the Zeus-Link and external contacts to light a dash light
• System queries vehicle upon installation to determine what list of parameters can be obtained from the vehicle and used as inputs to gauges
• Holley harness has additional Holley ECU connector for other devices
• All instruments can be driven traditionally through proper senders if vehicle ECU does not support an output the driver wants to monitor
• The app has easy diagnostics, displays values being received by Zeus-Link and will allow user to cycle gauges to predetermined positions, to verify correct outputs and wiring
• Dash light connection
• All gauge connections to Zeus-Link (power, ground, signal, dash lights)
• The app has a virtual gauge screen, aligning with the dash instruments
• Compatible with all Classic Instruments sending units and gauges
• Spaces for 6 standard gauges: speedo, tach, fuel, oil, volt, temp, and 2 auxiliary gauges of the customers’ choosing
• Pass-through CAN port connection for other CAN devices
• Harness plugs direct into Zeus-Link and then to Holley ECU or OBD
• Additional resistor dongle available if needed to use multiple Holley CAN devices on the same harness
• The app is used to configure by choosing which gauges a customer has in the dash and how each gauge gets its signal
• Set up and managed all through an app available on the App Store® or Google Play®
• On-board diagnostic lights give status of power, BLE, and data on the circuit board for Zeus-Link
