Below is what your installation manual says. Basically it's telling you the blue lead is a signal lead only to signal your antenna to raise or lower if you have this type of antenna. If you don't then don't use the blue lead. The blue/white lead is a signal lead to signal an external amp to turn on if you have one. If you don't then don't connect this lead to anything. Neither of these wires are power leads, they're only signal leads and aren't to be used to try to power anything. I don't see where there's any conflicts here.
Notice for the blue lead
- A signal is output through the blue lead to
control the antenna of your vehicle. The
timing varies depending on the setting. (For
more detailed information on changing
[Ant CTRL] mode, refer to “Operation Manualâ€.)
- When [Ant CTRL] mode is set to [Radio],
the vehicle’s antenna can be stowed or
turned off by following the instructions
below.
— Change the source from radio (AM or
FM) to another source.
— Turn the source off
— Turn off the ignition switch (ACC OFF)
- If [Ant CTRL] mode is set to [Power], the
vehicle’s antenna can be stowed or turned
off only when the ignition switch is turned
off (ACC OFF).
- Do not connect this lead to the system control
terminal of external power amps.
- Be sure not to use this lead as the power
supply lead for the auto-antenna or antenna
booster. Such connection could cause
excessive current drain and malfunction.
Notice for the blue/white lead
- When the ignition switch is turned on (ACC
ON), a control signal is output through the
blue/white lead. Connect to an external
power amp’s system remote control terminal
(max. 300mA 12 V DC). The control signal
is output through the blue/white lead,
even if the audio source is switched off.
- Do not connect this lead to the auto-antenna
relay control terminal or the antenna
booster power control terminal.
- Be sure not to use this lead as the power
supply lead for the external power amps.
Such connection could cause excessive
current drain and malfunction.
