Harness Details
This section covers the LCU Harness details. The QwikData 2 Data Acquisition System is available in three
configurations; Basic , Advanced Thermocouple and Advanced Analog . Harness schematics, pin-out
designations and connector details for each system are available in this section. These details may be useful
when setting up your QwikData 2 system.
To make the installation as easy as possible, the wiring harness provided is completely assembled with
connectors that mate to the supplied sensors. Each sensor is connected to the QwikData 2 unit by simply
mating the appropriate connectors.
Route the wiring harness as needed to make connections to the installed sensors. Avoid paralleling Data Log
wires with any ignition wiring (primary or secondary) To connect the circular connectors on the wiring harness
to the sensors, push the mating connectors firmly together and then turn the locking ring clockwise to lock the
connectors together.
Refer to Suggested Harness Routing in the Harness Detail Section for assistance with routing you harness.
With some installations it may be necessary to re-pin the LCU Connector in order to accommodate sensor
location and available sensor input types. In these situations it should only be necessary to move the Analog
Signal or Digital Signal wires in the LCU connector. The Sensor power and ground wires are all common. To
release the pins in the LCU Connector simply depress the single white rectangular shape button on the LCU
Connector. Re-locate pins as necessary in connector then depress pair of white rectangular buttons on
opposite side of connector to lock pins.

The Basic System includes a single harness with 8 analog, 4 thermistor type temperature sensor, 1 Tach
Input, 1 frequency(digital) sensor connectors and 1 programmable switched output that all terminate at the 34
pin connector on the LCU. * Inputs 7-10 are configured for thermistor type temperature sensors.
ADVANCED THERMOCOUPLE HARNESS PART #91294
The Advanced Thermocouple System includes two harnesses; the Basic System Harness and a second
harness with 4 additional Analog sensor connectors, 2 frequency(digital) sensor connectors, 8 thermocouple
connectors and a additional programmable switched output that terminate at the 26 pin connector on the LCU.
* Inputs 7-10 are configured for thermistor type temperature sensors.
ADVANCED ANALOG HARNESS PART #91291
The Advanced Analog System includes two harnesses; the Basic System Harness and a second harness with
12 analog sensor connectors, 2 frequency(digital) connectors and a additional programmable switched output
that terminate at the 26 pin connector on the LCU. * Inputs 7-10 are configured for thermistor type
temperature sensors.
