I'm currently installing a new radio in my 1998 Ford Explorer XLT, and i've run in to the issue of none of the wiring connectors i've used will fit. What will happen is I'll get power, signal, etc, but no sound. I know for sure the pins inside the connectors do not line up. My explorer was manufactured in May 1998 and on a long shot I looked at the 1999 connectors, but they will not fit. Also, I have looked at the 1997 explorer connectors and those seem to look like they will fit. I am going to a Car Audio shop on Monday, but any suggestions on what to get, or do?
