LS 4
A17
A/C Clutch Relay
Lowside switch, 4A max, No
internal f ly back diode.
See Setup Wizard Page "LowSide Assignment
Tables" for output assignment and 2D table
"LS4_Duty [%]" f or on/off activation.

LS 5
A19
Engine Speed Pulse
Lowside switch, 4A max
with internal flyback diode.
Inductiv e load should NOT
have f ull time power.
The tachometer is pre-calibrated using a
combination of the LS5_Freq [Hz] 1-axis table
and the LS5_Duty [%] 2-axis table.

A1
Engine Coolant Temp
Gauge
Lowside switch, 4A max
with internal flyback diode.
Inductiv e load should NOT
have f ull time power.
The coolant temp gauge is pre-calibrated using
the LS6_Freq [Hz] 1-axis table and the
LS6_Duty [%] 2-axis table. This signal is
pulled up to 5V.
