data, serial GPS data (SIU aircraft only) and power in a single connector. An adapter
harness p/n 4370-9630 is available to plug directly into P528.
Installation in DAU equipped aircraft will be the same regardless of whether the MFD is
fitted or not, as the MFD connector P528 in DAU equipped aircraft does not receive GPS
data over RS232, so connection via P528 is not recommended.

Parts required
Installation of BlueMAX requires the BlueMAX module and an adapter harness which
connects it to the aircraft wiring. The harness for SIU and DAU aircraft are different –
order the correct parts as listed in Table 4: BlueMAX part numbers. The kit part
numbers include the BlueMAX module and the appropriate harness and connectors
(where necessary.) In addition, there may be cable ties, wire, splices and other common
electrical parts required – these are not included in the kit.

Standard tools will be required.

Probing connector P1426B
If it is required to probe the connector P1426B (this is the one that plugs into the
BlueMAX module) to confirm continuity or measure power supply voltage, do NOT
insert a probe into the pin opening as this will damage the terminal. Use a fine probe
(0.66mm or smaller) in the probe opening below the pin opening – see Figure 3: Probing
P1426B.
