How do I replace the factory radio in a 1993 Ford Explorer?

Answer 1

Here is your solution:

Purchase a Scosche harness kit #FDK2b, which supplies the rectangular connector for power, ground, etc.; a square connector for the 8-pin speaker/amp connections; and a double-ended AMP BY-PASS connector. You have to have this connector (also sold separately as fd07b) to properly by-pass the factory amp, which will redirect the speaker connections from the 8-pin speaker/amp connector direct to the factory speaker wiring in the doors.

I would recommend using these harnesses 1) if you are planning on re-installing the factory radio prior to selling the vehicle, or 2) if you do not want to take the time to re-wire for speakers.

Re-wiring for speakers is the BEST method; however, I have installed in these vehicles more than once, and it is very tedious and time-consuming work to properly route quality cables through under-carpet channels, door sills, factory cable routes, and door harnesses. Seriously, unless you are installing a kick-butt system with multiple amps, subs, and dozens of speakers, it is not worth the effort.

If you are simply replacing a defective head unit, or upgrading to a "better" head unit, use the harnesses I've listed above, and your installation will take about 30-minutes.

Pre-connect the rectangular and 8-pin harnesses to your replacement head unit's wiring, remove the factory head unit using Ford Radio removal tools (available at most auto parts stores, Wal-mart, online, and Scosche also has a universal radio removal kit), disconnect the two harness connectors and antenna connection, and install your new unit according to the manufacturer's instructions.

To by-pass the amp, locate the right-rear fender panel located in the cargo compartment on the right side of the vehicle). It is best to do this from inside the cargo area. Lift the carpet and locate and remove the two screws which secure the plastic fender panel to the floor, gently remove the panel by popping the plastic anchors (careful not to damage them) which secure the panel to the side of the body. Pull the panel back enough to reach the amp (there is no need to fully remove the panel), disconnect the two connections to the amp, and connect the jumper harness between the two connections you just removed. Re-assemble the interior panel and you're done!

The entire process should take 30-60 minutes.
