Thank you very much saved a lot of time. Good work, Pannie c.
Pannie, we are glad we could help you with your 2011 Ford Fiesta stereo wiring diagram needs.
All, I’m not sure what I am doing wrong, but the brown/white accessory wire is not showing 12V for me with my volt meter… I know there are two brown/white wires (one is for the speaker), but I am having no luck finding a remote wire that I can connect to my external amplifier… any advice is appreciated.
Matt, technically you could connect your 2011 Ford Fiesta amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2011 Ford Fiesta is on and off whenever your 2011 Ford Fiesta is off. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good luck with your 2011 Ford Fiesta amplifier install.
What i did with my fiesta was run a power cable with an inline fuse right from the car battery to one of the cable openings in the firewall all the way under the trim panels into the trunk. Wasnt too hard to do. Then i just connected an rca converter to the factory stereo and connected the amps rca cable to it. Vwalla
Jester01, thanks for the 2011 Ford Fiesta amplifier power cable installation information contribution!
Do you know what brand of head unit they placed in the fiesta? What is the min and max output of the deck? Does it have aux input for RCA plugs? How about the speakers what size did they put in the front and in the rear?

Very nice. Much appreciated for all this. Any chance you could get a diagram of the pins at the back of the radio as I have the radio but need to know which pin does what as I don’t have the cables in the car. Thanks, Mike.
Michael, as much as we would like to help you, most of the car stereo wiring information listed on our website is provided by our visitors. We currently do not have any information on the 2011 Ford Fiesta pin out diagram but hopefully someone from our knowledgeable Modified Life community would be able to chime in and assist you.
Where is the best location to run the power cable pass thru the firewall of my 2011 Ford Fiesta?
Carlos, most vehicles have a factory hole with a rubber or plastic grommet at the firewall. This is usually the standard place to run a power wire through the firewall. If one of these holes are not available or not large enough, a hole will have to be drilled to accommodate your power wire. Choose something on the engine side of the firewall as reference and try to match it up on the interior side of the firewall. This will make sure you do not drill through anything important. Then drill a hole somewhere near or beside your reference point. Make sure to use a firewall grommet to prevent the power wire from chaffing on the firewall that could potentially cause a short. Hope this helps. Good luck with your 2011 Ford Fiesta amplifier installation.
Anyway to find out wiring for an alarm system. I have a 2011 Ford Fiesta S model sedan that doesn’t have remote entry. I have a viper 211hv system that I plan on using only for remote door locks. However not sure which wire is the lead for the locks. That’s all I need for info is the lock wire. Thanks for the help
