The Rotax harness only has EGTs 1 and 2 wired, as the EMS measures the Rotax-supplied
resistive CHTs through its GP inputs. The four-cylinder harness only has EGTs 1 through 4 and
CHTs 1 through 4 wired. On the supplied harness, each pair of wires is encased in brown
insulation and labeled with corresponding cylinder number. Inside the outer insulations, each
wire in the pair has the color listed in Table 16 and Figure 30.
If you make a custom thermocouple harness, note that all differential
thermocouple inputs on the D25 and the D37 (SV-EMS-220 only) connectors are
compatible with both J and K type thermocouples. Note that you will need to
