Re: Remove door chime?
Yes, I have had this one installed in my 2003 for several years and it works great.
Here is a newer version of that same mod that has been successfully done on a couple of 2004's. It should work just as well on all 2004~2006 Rangers but, as always, proceed at your own risk.
(Note that 2007 and later use different wiring and color codes so neither of these will work as shown.)
