Wiring Connections
1. TV TUNER
2. ANTENNA
3. POWER ANTENNA WIRE (Blue) – Connect to a motorized (power)
antenna and/or to a remote turn-on lead for an amplifier.
4. CONSTANT POWER WIRE (Yellow) – Connect the 12V PLUS constant
power wire to a live 12 volt wire in the vehicle. Before making a connection,
check that the wire you intend to connect it to is always live, even when the
car’s ignition is turned off. If a live wire is not found, route the wire to the
car’s fuse block and connect it to a live circuit there.
5. GROUND WIRE (Black) – Securely fasten the Ground wire to a grounded
metal part of the car’s chassis. If you cannot find an existing bolt or screw
to fasten it to, drill a hole in the metal and secure it with a screw. To ensure
a good ground, remove any paint or grease from areas where the wire will
contact the surface.
6. PARKING (Pink) – Connect to negative parking brake wire. This wire
MUST BE connected in accordance with federal, state and local laws. It is
the end-user’s responsibility to make sure this wire is connected properly.
7. ACC POWER WIRE (Red) – Connect to a +12 volt circuit that is only live
when the ignition is on. The best connection point is at the car’s fuse block
at the “RADIO” or “ACCESSORY” identified terminals.
8. LEFT FRONT SPEAKER (white, white/black)
9. RIGHT FRONT SPEAKER (gray, gray/black
10. LEFT REAR SPEAKER (green, green/black)
11. RIGHT REAR ( + ) SPEAKER (violet, violet/black)
12. FRONT AND REAR RCA OUTPUTS
13. CENTER RCA OUTPUT (Gray) – The center output must be connected to
an external amplifier for 3D or 6-CH mode.
14. SUBWOOFER RCA OUTPUT (Blue) – The subwoofer output is available
in all sound/audio modes.
15. DEDICATED DVD OUTPUT – Video output for rear screen and left/right
audio output for headphones.
16. AV1 INPUT
17. AV2 INPUT
18. VIDEO OUT (Yellow) - V. SEL output for rear screen.

MAY THIS HELP YOU

Do you have the harness adaptors? it is best to use these rather than cutting harness. you can swap factory radio back in at later date and they will tell you the wiring ,if not i will try and locate the diagram for you

(There are different versions of the ba-200, so I'm assuming they al use the same wiring/pinout...) if you look at the amp on the enclosure(right-side up... so the writin goes left->right): The top left pin is #1, beside it is #2, then #3. The bottom left pin is #4, beside it is #5, then #6. #1 Right speaker positive input #2 Empty #3 12 Volt Constant Power #4 Left speaker positive input #5 Remote turn on / Acc power input #6 Ground Now there's supposed to be a 15-amp fuse on pin #3 (12v constan power).
