INSTALLATION
For most electronic engines, the TACHPLUS+ receives engine RPM, oil pressure,
and coolant temperature information over the J1587 data link from the engine ECM.
Some engines do not broadcast complete engine information over the data link and will
require that seperate sensors are installed.
Install Control Module
1. Measure and mark mounting location for control module panel cutout and
mounting screw holes. Make sure there is clearance behind the panel for the
module and cables before cutting holes. Refer to Figure 2 for layout and
dimensions.
2. Cut out a 3.75-inch diameter hole.
3. Drill four holes, clearance or tapped, for 10-32 mounting screws.
3. Place control module in position and secure with screws.
4. Connect cables at rear of the contol module. (Refer to Wiring section.)
Install Buzzer
A buzzer is supplied with the TACHPLUS+. Install the buzzer close to the control
module so the audible warning is easily associated with the visual warning on the
display. A cutout hole of 1-1/8" (1.125") is required on the pump panel. (Refer to
Wiring section.)
