Wire in a new radio
Wire in a new radio
Crux's SOOFD-27C interface ensures that you can keep the factory speaker system in your Ford, Lincoln, or Mercury vehicle when you replace the factory radio. Connect the wires from this interface to the wires on the new stereo's wiring harness, and your power, ground, and factory speaker connections are covered.
The SOOFD-27C interface also offers the reverse output that you'll need if you're installing a navigation receiver. If you like your radio to keep playing after your vehicle is turned off, this interface also supports Retained Accessory Power (RAP) which keeps the music going until the door is opened.
Important Installation Notes
The SOOFD-27C interface is not compatible with factory SONY systems or the THX amplified systems.
Product highlights:
- connect a new stereo to your factory wiring plug and keep your Retained Accessory Power (RAP) feature

Retained Accessory Power (R.A.P.): The ignition power source of many Ford/Lincoln/Mercury vehicles keeps the radio on until one of the doors is opened. This feature is called the R.A.P. (retained accessory power). The CRUX SOOFD-27C is designed to retain this feature.
Wiring Harness: The included wiring harness features 16-pin and 24-pin molex connectors that plug into your vehicle's factory radio harness, plus a 8-pin connector which plugs into the SOOFD-27C interface module. The wiring harness also provides the following bare-wire leads which will need to be hardwired to your aftermarket head unit's wiring harness.

Perfectly fits for Ford F150 2009 XLT. I used this interface with my aftermarket unbranded Chinese navigation/DVD player with backup camera. Everything is working flawlessly. After researching so many hours, I decided to buy this one. Its easy plug and play.
