Average Customer Review(s):
Perfect for my 94 Cadillac fleet wood brougham.
Wires for plenty long everything plugged in just as expected
Pros: Ease of installation straightforward instructions
Needed this item it was a lifesaver
Pros: The best
Installed in a 1995 Cadillac Seville SLS. Known to be an absolute "pain in the foot" to repair (even GM mechanics complained which brought a complete re-design by GM two years later), installing this wire harness was not only painless, but effortless. Extremely well made.
Pros: Easy Install, Quality Product
Used for a 1994 fleetwood and made installation a breeze. I wrapped it in electrical tape to keep it all together during i stall
Pros: Makes DIY car installation easy
Made the install of my new Kenwood DDX471HD so easy, it is a must have for anyone.
Pros: easy to install, great quality
This wiring harness was a lot if wire, probably about 10-12 feet worth. Had to obviously trim some, but got the job done.
Pros: Plenty of wire length.
Cons: Simply to much wire.
This wiring harness does not match that of my 1993 Cadillac Sedan Deville,therefore can not use radio. It is missing one port.
Pros: Have none at this time.
Cons: Not functional.
You can buy this or make it and it's going to be such a bear to install this wire bundle that you may as well give yourself a little break and buy this part. I installed mine in a 1995 non-bose Eldorado. The installation instructions were too general and I had to ask for help on the Cadillac Forums. The harness plugged into my CDM box in the trunk by the power antenna and the other wires all mated up perfectly with my new radio once I got them routed to the front of the car. There is was no way to install a modern head unit in my car without this part so I give it 5 stars as it was required and not optional for me. I ordered a crimper with it to get free shipping lol. I have photos but no video of it.
Wiring Harness: This wiring harness prevents you from having to cut your vehicle's factory radio plug when replacing your factory radio with an aftermarket head unit. Simply solder or crimp the wiring harness to your aftermarket head unit's harness (solder & crimps not included), plug the aftermarket head unit's plug into the rear chassis of the aftermarket head unit, and plug the wiring harness into your vehicle's factory radio plug.
Note: Installation tools, hardware, & accessories are not included & sold separately. Please see the Accessories tab for recommendations & availability.
Wiring Notes: If the wiring harness is not equipped with a ground wire, you will need to ground the aftermarket head unit's ground wire to the metal chassis of your vehicle. Some vehicle's may require you to bypass the vehicle's factory amplifier (in another location from factory radio) or hardwire certain connections. If your vehicle is equipped with factory steering wheel controls, an additional adapter is required and sold separately.

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team. They verify what’s in the box, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.
The Metra 70-1856 Bypass Harness is the only option we offer for a 1993 Cadillac Fleetwood. Our research file notes "The factory radio has a remote tuner module mounted in the trunk. Any electrical connections will need to made there and then all wiring will need to be extended back to the dash location." For more details or assistance, please feel free to speak to an Advisor by phone (888.955.6000) or online chat ("Contact Us" link at the top of the webpage). I hope that helps!
