I have the stock cassette player out of my 98 f150 that I am switching out with a CD player out of a 98 ranger but the wiring harness is different. Where can I get a harness that would connect the two?

 

Do a Google and find the Scosche web site. There you can find the part numbers for the two wiring harnesses you'll need. You'll need to splice one harness that connects to your new head unit to another harness that connects to your truck's wiring. I build these all the time.

You can do another Google to find out who sells the harnesses. Some place like Millionbuy.com would probably have both for about $5 each.
