Installation Suggestion:   
 
Turbocharged engines: 1.5” upstream of the Turbine inlet with sensor axis in the vertical Plane and sensor end down. 
 
Naturally aspirated: 1.5” downstream of the collector or end of exhaust manifold in the same configuration as for 
turbocharged applications. 
 
Wiring: The wiring for the unit is simple and consists of only 2 wires. Polarity is not important. For the 30-1000, 30-1001, 
30-1002, 30-1010, 30-1012, 30-1020, 30-1100, and 30-1101 units, connect 1 wire to 5 volts and the other to an open EGT 
input channel on the EMS. On all other EMS units, connect 1 wire to a good ground and the other to an open EGT input 
channel on the EMS.
