Thx robot.. The concept of switching to ground or from active is now understood by me. One giant step for mankind.
Here's our FujitsuTEN h/u
As it is not easy to read the pins, after much reading and peering I believe the following is true but I'm sure you will know if I am wrong:
Fujitsu Ten Head Unit
4-pin section CN4950
This is where I have my rear camera working fine
10-pin section of CN1 power/speaker harness
1 2 - - 3 4
5 6 7 8 9 10
(orientation: viewing pins on car's factory plug, wires pointed away from you)
Code:
1 RF+
2 LF+
3 +12V Accessory
4 +12V Battery/Constant
5 RF-
6 LF-
7 Ground
8 Power Antenna (provides power to Subaru's antenna booster amp)
9 [NC] {amp remote turn-on signal on Toyota HUs, not Subaru}
10 Illumination+
6-pin section of CN1 power/speaker harness
1 - - 2
3 4 5 6
(orientation: viewing pins on car's factory plug, wires pointed away from you)

3 RR-
4 [NC]
5 Dimmer (Illumination-)
6 LR-
28-pin CN6 SWC/aux/mic harness
1 .. 14
15 .. 28
(orientation: viewing pins on car's factory plug, wires pointed away from you)
Pins with wires from the plug are marked
green
Code:
1 [NC]
2 Reverse Gear PIN 2 = Reverse gear IN. Although it comes in here it seems to tell CN4950 and CN4800 if reverse is selected
3 Illumination Dimmer Cancel (Bright mode)
4 Mic ? (separate, possibly ground)
5 Mic ? (twisted w/ 19)
6 Ground (not connected to mic)
7-10 [NC]
11 GND
12-14 [NC] 13 might be a VIDEO in and 14 the shield I have no wires to these
15 [NC]
16 [NC]
17 SGND VSS (vehicle speed signal)
18 SGND [NC]
19 Mic ? (twisted w/ 5)
20 [NC]

23 SWC Common
24 [NC]
25 ADPG Aux enable
26 VAR+ IN Aux audio Right
27 VA- GND Aux audio shield/ground
28 VAL+ IN Aux audio Left
16-pin rear camera socket
1 ... 8
9 ... 16
(orientation: viewing pins on car's factory plug, wires pointed away from you)
Code:
4 ? function unknown
5 ? function unknown
6 Parking brake grey wire The parking brake signal is used to block display of movie video (from USB movie files or DVD) or the aux video input. It may also be used to temporarily disable certain menus that the car or HU manufacturer deemed to be too distracting for the driver to use while the car is moving. It can be left connected or disconnected.
7 Camera +6V supply (HU sends power to OEM Camera)
8 Camera Video In
11 BTCY In ????? =
15 Camera Detect (I have read the h/u connects this pin to ground internally. I cannot understand how the camera is detected as simply having a camera connected is enough) I have no wire to it.
16 Shield/ground
