Can I wire my new radio to the factory radio harness if I cut it

There are bypass cables available so no cutting or splicing required. Your search for amplifier bypass harness returned the following

I would spend the few bucks and purchase the install adapter. It will save you time and having to cut up the factory harness.

buy a harness .. much safer , without cutting factory wires

It sounds like your speaker wires are touching each other. Was the factory radio an Infinity? They have an amp on each speaker and do not work with aftermarket stereos. Do you have power to the unit? I really need more info to be much help. Your best bet is to buy the radio end wire harness from stereo store, walmart, radio shack or dealer if you didnt cut the truck end off. They only @ $10. Then it is so fast & easy you will never cut the harness out again. Get back to me if you still need help. Good luck and I hope this helped you.

The stereo in Ford products comes out with a special tool, Which you can find at a place that sells car radios. Remember that Ford used a Premium JBL/Philco stereo in your car at the factory.
Connecting subwoofers and power amps means going to the main fuse box under the hood rather than the smaller one in the cabin. You may actually wind up running a power feed directly from the battery. I would then buy one of the harness adapters from a stereo shop to match the new radio and equipment into my system. They come with instructions so that you so not have to butcher your wiring harness to install a new radio and speakers.
Comment: Over the years, I have seen some very nice cars depreciated in value when the owners cut into the harnesses to install sound ewquipment and made a mess of it. Use caution.

This is the most common problem with self installs.The best thing to do is to get the car radio installation plug,it will plug into the factory plug for your factory radio and will give you a color coded pigtail to wire into that usually matches up perfectly with new aftermarket car radios.If the wires are already cut then you best bet is to extend the wires so that they are easy to work with hookup the power,ground,antenna and try dirrerent combos to isolate each speaker and label the wires accordingly.

Very simple. DIN size head units fit without any adapters (assuming your car has the DIN size factory radio with pocket underneath {I have '93 Paseo and this was the setup of mine, though Crutchfield.com shows option of factory stereo with pocket and without [guessing there was a double DIN size option]}). All you need is a wiring harness. I've seen these anywhere from $5 - $20. This will connect to the wires on the harness for your new radio, then instead of cutting any of the factory wiring, you simply plug the factory harness into this new socket.

The trim ring around the radio/climate control/ashtray area is held in with clips. It just pops out (may have to use a thin screw driver to get your fingers under one of the edges to start). Four screws hold the metal frame where the head unit, climate control, and ashtray are. Take those out and pull the metal frame out a bit, then disconnect the wires of the climate control, power lead to lighter, and stereo harness and antenna. Two screws per side hold the stereo in to the metal frame. Take those out, slide out the factory radio and put in your new head unit (You will not use the metal cage or any other mounting brackets the head unit may come with). The holes on the metal frame should line up with mounting holes on the side of your new radio.

Not to endorse one vendor over another, but Crutchfield.com supplies instruction sheets and any needed install accessories free with purchase of new head unit. Their prices are often slightly higher than you can find elsewhere (comparable to retail stores, usually more than online stores), but you get the wiring harness and instruction sheets for your vehicle. At the very least, you can use their site to see what fits your vehicle (Note: Many other stores do this as well.)
