## Questions & Answers

**Q: Will this work in my 2005 Ford Excursion?**
A: I'm a ford fanatic and from my experience is that for a certain amount of years they use the same connectors as long as u don't have a premium system from factory...this product fit my 2005 focus with stock (not premium) stereo...triple check before purchase don't take my word for it.... but u can always return if need be...

**Q: Is there a wiring diagram**
A: Yes it was easy to connect to my f150

**Q: What is the right harness to use for boss elite 765blc stereo in 2006 ford 500 limited**
A: I would say Yes. This harness worked for my 2007 Explorer and matched the factory radio connector perfectly. You may not use all the wires on this harness depending on which Ford radio you are replacing.  Makes installation a lot easier!

**Q: 2006 ford explorer
Are the wires tagged?**
A: If you are asking if they are labeled to where they need to go then yes. It tells you front positive and negative, rear positive and negative, remote wire for amp, power antenna etc. Red wire is switched 12v and yellow is 12v constant for memory. Very easy to wire up. I hope this helps you out and answers your question. :)
