Our take on the PAC RP4-FD11 Wiring Interface by Crutchfield's Jon Paulette
PAC's RP4-FD11 radio replacement interface lets you replace the factory radio in select 2005-up Ford, Lincoln, Mazda, and Mercury vehicles. You'll still retain your factory steering wheel audio controls, rear seat entertainment (RSE) system, retained accessory power (RAP), and the use of your Ford factory amplifier, if present.
The RP4-FD11 interface eliminates the need for the steering wheel audio control adapter that's usually required for a Ford-built vehicle, saving you some more cash. Warranty: 1 year.
Important Note: You'll lose your fader control if you have an amplified system in your vehicle. The RP4-FD11 adapter does not work with your SYNC system; you'll need PAC's MS-FRD1 adapter to maintain that functionality. See Details for a list of compatible car stereos.
Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this model is compatible with your vehicle.
Note: Most vehicles will require additional installation parts please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.
Works as advertised. Installed in to a 2011 Escape XLT. All I had to do was solder the wires (FOLLOW INSTRUCTIONS AND TRIPLE CHECK!), set the dial to 7 for a Pioneer radio, plug it in, and go. Was quite enjoyable for me to install myself.

PAC RP4-FD11 Wiring Interface Reviews
Average Customer Review(s):
Thanks for submitting your review
Overview: The RadioPro4 (RP4-FD11) is a radio replacement and SWC (steering wheel control) interface that comes pre-loaded with amplifier retention and SWC software, navigation based output signals, and firmware that retains all of the vehicle's original safety and convenience features when replacing the factory radio with an aftermarket head unit.
Functionality: The RP4-FD11 interface allows the replacement of a factory radio in select Ford/Lincoln/Mercury vehicles with the CAN-bus system. Using this interface will retain factory features such as steering wheel controls (SWC), rear seat entertainment (RSE), rear seat control (RSC) and, the factory audio amplifier whenever the original radio is removed. The RP4-FD11 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake.
Note: If the vehicle is equipped with the Sony factory stereo system, adjust the fader to your preferred front/rear setting before the factory radio is removed. Neither the aftermarket radio nor the RP4-FD11 interface has the ability to adjust the factory amplifier's fader. The RadioPro4 (RP4-FD11) does not retain your vehicle's factory SYNC system. SYNC retention requires the PAC MS-FRD1 radio replacement interface (541MSFRD1, sold separately).
Vehicle Compatibility: The RadioPro4 (RP4-FD11) is compatible with select 2005-up Ford, Lincoln, Mercury vehicles with MSCAN databus radios. Compatible vehicles as of 7/13/2012 include:
|Explorer Sport Trac||2007-2010|
Vehicle Specific Notes: Not compatible with 2008 F-250/350/450 with XL trim (fleet vehicles). Only compatible in base model 2013-2014 F150 trucks equipped with the center stack radio.
Radio Select Switch: The radio select rotary switch on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the vehicle.

SWC Compatible: The interface comes pre-programmed for all of the vehicle's factory SWC functions and does not require programming, unless you wish to re-assign the SWC functions to different buttons. The SWC functions can be easily programmed; see control settings and functions below. The interface retains programming even if your vehicle's battery is disconnected.

Not compatible with Soundstream head units.

5 answers i have a 2008 Escape XLT, which does not have SWC (just cruise control) or a factory amp. is this item overkill or can i just buy a wiring harness? it's been a while since i've installed a car stereo, but i've never had to use one of the blue things before. usually a $10 wire harness covers it. Thanks. [ dave13 Nov 23, 2014 ]
Yes, this is not necessary for your application. [ JOHN W Nov 26, 2014 ]
David, I don't now why you would want this PAC RP4-FD11 interface? This is basically for SWC (steering wheel control) and it worked great for me! I didn't spend $149 on it either!!! I just bought PAC RP4-FD11 05-Up Ford/Linc/Merc interface/SWI Item #: 541RP4FD11 for my Daughter's 2006 Milan and it worked GREAT with the JVC KWR500 CD Receiver. You do have to pair them up at the end BEFORE you push everything back into the dash! I would THINK just the Ford/Lincoln/Mercury Kit Late Models, DD or the Ford wire Harness for Ford/Linc/Merc/Hyun 03-up woukld be all you need plus the Chrysler/GM/Ford Antenna Adapt Motorola M to OEM antenna F hook-up. I used to install radios in cars back in the 70's, Boy, times have changes with easier hook-ups with cable plugs! Whew,,,,,,,, my neck would be sore back under those dashes! lol. I had no problems but YOUR hook-up should be easier with out SWC and NO amp! Good Luck and use your cell phone to call their Install Support Team, I am sure they will help you out if you get stuck? [ TOM Nov 24, 2014 ]
This is just if you have steering wheel switches to turn up volume, source, or change channels. If you do not have those on steering wheel you don't need this item. I have a 2010 Edge with steering wheel controls and had to have this to operate radio from the steering wheel. [ CHAD Nov 24, 2014 ]
You only need it if you have steering wheel controls and want to use them for the aftermarket stereo. I have the steering wheel control for the stereo but decided not to use this, since i could just as easily reach the stereo. Your cruise control will still work without it, so you will have no use for this. [ JAMES Nov 24, 2014 ]
I purchased this to retain the steering wheel controls, factory amp, and factory auxilary imput. Without needing those, i dont see any reason why you would need this interface. The regular wiring harness should suffice. [ JASON R Nov 24, 2014 ]
2 answers Hey I have a question for all using the product. If you were to do this after it was plugged in are you able to unplug the interface and do the process again? I'm not getting anything out of my SWC at all. ** Radio Select Switch: The radio select rotary switch on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the vehicle.** [ tdotswins Oct 16, 2014 ]
Presenting the interface is mandatory for the head unit to work. Read the instruction provided with the interface to correctly set your radio up. [ PETER May 13, 2016 ]
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Krissy Oct 20, 2014 ] Staff
1 answer Will this allow the upper LCD display to show the currently playing sing title information on my 2008 Escape hybrid. I see from Kelly's answer that it displays the time, and temp info but will the 2-line display on the upper screen show text/title info for currently playing track? Thanks. [ Leo Jun 10, 2014 ]
My understanding is the head unit controls what is displayed, this just allows you to use the steering wheel controls to work with the aftermarket head unit/ stereo. [ JAMES Jun 10, 2014 ]
6 answers Hi ... did you install the PAC RP4-FD11 in a 2010 Ford Fusion? I recently installed mine that I got from CrutchField. It works well and all SWC functions are fine. What I have question about is if your LED screen (my car is SE model) shows the clock anymore? I lost the clock display functionality, plus it always shows "DVD" in upper corner. Just wondering if this is typical behavior with other people. Thanks. [ Eric Jan 16, 2014 ]
Actually I ended up returning mine. In the end I could not justify the money and the cuts to the wireing harness for the stearing wheel controls. I can reach the stereo as easily as I can reach the steering wheel controls. I would not expect that to be normal behavior, since my understanding was that this would make your steering wheel controls work like a remote. Not that it would come in as a seperate line-in. This might be worth asking Crutchfield or anyone else running your stereo. On a side note, did you make the same mistake on the wiring so that your stereo does not dim with the interior lights? Ford uses a different wire than the harness shows. I need to go back in and make the change, but waiting until a nice warm day and that I feel up for it. Good Luck [ JAMES Jan 17, 2014 ]
I was sent this question, but I'm sorry I can't offer any assistance. Mine was in an explorer that didn't have the screen. Put in your car, go to stereos, and click in the top bar. It has "important info" about you particular car. Should describe if that screen will or will not work with an aftermarket radio [ JASON R Jan 17, 2014 ]
I did have my head unit installed by a local shop this time. My 2012 Escape Limited has the LED screen on the upper center dash as well. Mine shows temperatures, outside temperature, direction and it reads "Audio" and in upper left it reads "DVD" [ KELLY Jan 17, 2014 ]
I do not have the car anymore but if I remember right, it did knock out the clock function like you say. [ EVAN Jan 17, 2014 ]
I have a 2007 ford explorer, have no problem......maybe wiring? [ ERIC Jan 17, 2014 ]
I did some research prior to the install and found that some features stop working intermittently and that the clock feature from the screen does not work. I decided to not use install it because of the integration it requires. Since then I have sold the fusion and bought a new vehicle. Sorry I could be of more help with your issue. You could always try contacting a reputable car audio store. They should be able to help you without any fees. [ NICHOLAS J Jan 17, 2014 ]
