To install a VDO Dayton CR 1004 without a plug-in power unit at the back, follow these steps:

1. Gather Materials:
- Wiring harness with ISO connectors (if available)
- Power cables (12V constant and 12V ignition)
- Ground wire
- Speaker wires
- Antenna cable
- Electrical tape or connectors
- Multimeter (to test wires)

2. Identify Wiring:
- Use a wiring diagram for the CR 1004 to identify pinouts.
- Typically, red = 12V ignition, yellow = 12V constant, black = ground.
- Speaker wires are usually paired by color (e.g., white/white-black for front left).

3. Connect Power:
- Connect 12V constant (yellow wire) to a source that always has power.
- Connect 12V ignition (red wire) to a source that is on only when the ignition is on.
- Connect black wire to vehicle chassis for ground.

4. Connect Speakers:
- Connect each pair of speaker wires to the correct speakers, matching polarity (+/-).

5. Connect Antenna:
- Plug the antenna lead into the antenna socket on the back of the unit.

6. Secure Installation:
- Mount the unit in the dashboard.
- Ensure all connections are secure and insulated with tape or connectors.

7. Test Functionality:
- Turn on ignition and test power, radio, and speaker output.

If the OEM connector is missing, you may need to manually wire the connections to the appropriate pins on the back of the unit using spade connectors or a custom harness. Use a pinout diagram to match each function correctly.
