Installation
The ZR-3 AFR Gauge works with all Zt-2 and Zt-3 Wideband Systems. The ZR-3 Gauge plugs into the Zt-3/Zt-2 DATA port. Power and serial data is supplied directly through the single connection - there are no additional +12V or ground wires. The ZR-3 cable length is 5 ft (1.5m).
Mounting
The ZR-3 AFR gauge is only 6/8" (19mm) thick. The back of the gauge is completely flat with cable hidden in a cavity and can be surface mounted almost anywhere inside the car cabin using a piece of Velcro or double sided tape. The ZR-2 base allows the gauge to be mounted in a standard 2” 1/16 (52mm) gauge pod. For additional mounting options the package includes 2 set screws and 2 nuts (4-40 screw size).
