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.

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.

Q
What does this actually do? I don't really like the fact that my stereo stays on until I open the door. If I don't install this what else do I loose?
[ Frank Einstein  Dec 25, 2018 ]

A
I have this wiring harness and it's awesome. I have the 2011 F-150 and the only thing that I lost function wise was the steering wheel audio controls and the volume display above the unit in the center information area. Other than that great product.
[ WINFIELD  Jan 02, 2019 ]
A
That feature is built in the car. This just allows you to hook up without having to cut up the factory harness. It does not allow the use of steering wheel controls
[ Lewis  Dec 29, 2018 ]
Q
The 24 pin connector matches up with my vehicle perfectly, but what is the 16-pin connector supposed to connect to? And what does the little black box do? I don't see any wires in my vehicle that would plug into the 6-pin jack on the other side of this box, so should I omit it? The included instructions are no help.
