9. PINOUT SHOWN FOR PACKARD CONNECTOR SUPPLIED WITH KAVLICO PRESSURE TRANSDUCERS. WIRE COLORS ARE SHOWN
11. ONLY APPLICABLE TO SIX CYLINDER ENGINES.
10. IF MEASURING BATTERY CURRENT, PLACE THE SHUNT BETWEEN THE BATTERY POSITIVE TERMINAL AND THE BATTERY CONTACTOR.
IF MEASURING ALTERNATOR CURRENT, PLACE THE SHUNT BETWEEN THE ALTERNATOR B LEAD AND THE POWER DISTRIBUTION BUS.
13. TIT PROBES ONLY APPLICABLE TO TURBOCHARGED ENGINES.
8. SENSORS SHOWN ARE INCLUDED IN THE GARMIN 4 AND 6 CYLINDER SENSOR KIT P/N K00-00512-10 OR K00-00513-10.
14. ONLY APPLICABLE TO CARBURETED ENGINES.
12. NOT INCLUDED IN THE GARMIN 4 AND 6 CYLINDER SENSOR KIT P/N K00-00512-10 OR K00-513-10.
7. GROUNDING METHODS FOR ELECTRONIC TACH SIGNALS MAY VARY BASED ON THE MANUFACTURER. CONSULT THE ELECTRONIC
IGNITION MANUFACTURER DOCUMENTATION FOR SPECIFIC GROUNDING GUIDANCE. THE CAP FUEL 1/ RPM 2 INPUT (GSU 73) OR
6. THE RPM CHANNEL CAN BE CONFIGURED FOR UMA TACH SENDERS SHOWN OR 4 OR 6 CYLINDER ELECTRONIC IGNITION INPUTS.
15. LIGHT SPEED ENGINEERING PLASMA III "B" AND "C" MODELS REQUIRE A 2.2K PULL DOWN RESISTOR FOR PROPER OPERATION.
RPM 2 (GEA 24) INPUT CAN BE OPTIONALLY USED ON AIRCRAFT WITH DUAL ELECTRONIC IGNITION.
FOR REFERENCE ONLY. ALWAYS CONFIRM CORRECT SENSOR CONNECTIONS USING SENSOR MANUFACTURER DOCUMENTATION
BEFORE CONNECTING WIRES.
PLASMA III "A" MODELS AND PLASMA II MODELS DO NOT REQUIRE A PULL DOWN RESISTOR FOR PROPER OPERATION.
PLASMA III "B" AND "C" MODELS MODIFIED FOR OPEN COLLECTOR TACH OUTPUT ALSO DO NOT REQUIRE A PULL DOWN
RESISTOR FOR PROPER OPERATION.
