I just wanted to say thank you for having the diagram I needed for my Ford Ranger. It took all of like one minute to find it on your website. I’ve been looking all around for it on the internet and have been on over 150 website’s and yours is the only one that had it without any hassles.
Peter, we’re glad we could help you with your car stereo wiring diagram needs.
I’ve got a 2003 Ford Ranger Short Cab…I just bought four infinity kappa 5×8 speakers…I basically need to know how to take the door apart and wire everything?. I’m just doing basic speakers with no amp or anything. help would be much appreciated! thanks!
Macade, most door panel removals can be done with a Phillips screwdriver and by simply pulling the door panel off by hand. Just look for screws at the edge of the door panel, near the door handle or inside the door pull. Once you remove all the screws, you should be able to pull the door panel off with ease. Hope this helps. Good luck.
i dont have a light green wire for car battery. is there any other color they use?
I pulled out my stereo just to look at the wiring. does anyone know what the extra pins in the back of the stock rado are (2003 ranger XLT), or the gray harness connected to nothing dangling to the right (near the 12v plug)? Probably for some features I don’t have, but just wondering really.
