ODYR-25-1 & SLX-25-1 rev. A 

VACUUM/BOOST PRESSURE, TEMP, and EGT GAUGE 

 

SENSOR CONNECTION: 

 

The vac./boost sensor has 1/8” NPT on the end which can be treaded into the intake 

track, or into a pipe adapter with a barbed fitting and vacuum line to T-into a convenient 
vac./boost lines.  The sensor should be connected to the control unit as follows: 

RED   

Connect to control unit PWR terminal 

WHITE 

Connect to control unit BOOST terminal 

BLACK 

Connect to control unit GND terminal 

 

The temperature sensor is 1/8” NPT.  Senders can be mounted into the oil pan (a nut or 

collar may need to be welded to the pan) or T’d into an oil cooler line.  These senders have a 
tapered self-sealing thread.  The threads should all be cleaned before installation and no tape 
or thread sealant should be used on the threads.  Make sure that the sender tip can get into the 
coolant flow.  If the sender cannot ground through its threads then a ground will have to be 
connected to the sender case. Connect the supplied spade terminal to the top of the sensor and 
wire to the control unit TEMP terminal. 

The EGT sensor will need to be mounted in the exhaust system close to the engine.  Drill 

and weld the supplied bung to the exhaust. Connect the red wire to the control unit EGT RED 
terminal.  Connect the yellow wire to the control unit EGT YEL terminal.  Be careful to route the 
sensor cable away from any power or spark plug wires.  Wires routed along side the sensor 
cable can cause interference and incorrect readings.  Do NOT extend the EGT wires with 
normal wire, this will also cause incorrect readings and operation.  
 

Only use Dakota Digital sensors, sending units from other manufacturers may cause 

incorrect readings.
