Metra 70-1771 radio wiring harness adapter

Do not attempt to install a radio without a harness adapter. With this type of adapter you can do all of your wiring on the bench (or the couch) and then just plug it into the car's original harness. Safe, easy and fast. The 70-1771 works in Ford Crown Vics that are PIs, which do not use the 24 pin harness used by standard Vics. Sonic offers the best service, variety, shipping and price of these wiring harness adapters. The use of this harness will allow you to reinstall the original radio at a later date or if you need to reinstall if the new radio goes in for repairs. Even if you never need or want to put the old radio back in, this is the only way to keep your sanity when installing an aftermarket radio- and it's only $10 and free shipping!

Alpine UTE-73BT

Great head unit for a budget-friendly buy......way to go sonic.

By Casey on March 22, 2020 Verified purchase

Good value

This deck is reliable, easy to navigate, and provides great quality for a reasonable price. Way better than the cheaper Dual unit

Great value

I would definitely recommend this unit because gas so many great features such as complete control over your speakers especially if you have a subwoofer or 10 lol really easy to connect to Bluetooth and its sharp looking. The only complaint I would have is that it's only 2 volts? I recommend at least 4 volts for a bass system that's all besides that this is a steal!

Can’t beat it!

Can’t beat Alpine sound for only $99!!! Works as it should and sounds great. Fit perfectly in my 87 Buick Turbo T.

Alpine UTE-73BT

This was ordered to replace another brand that had quit working. The unit works well & was easy to install. Sonic was exceptional on covering the warranty from the old unit. Travis, whom I worked with was very helpful thru the process. I will definitely be buying for Sonic again in the future.

Used in a 2004 Mazda 3 worked as it should. Made wiring up radio easy.

By Fcss on October 22, 2016 Verified purchase

Great addition

Thanks for including this with the installation. What a great addition

Nice tough plug

The plug was fairly tough to hold up to locking and unlocking it also had long enough wires so you can cut them to your needs also the wiring is real copper, not cheap bi-metal so soldering was easy

By Gene on April 12, 2020 Verified purchase

Happy

I replaced my factory head unit expecting that my blown stock speakers would sound a little bit better, well come to find out they're not blown. They actually sound great now. Very satisfied with this purchase and it was on my doorstep within 36 hours.

By Richard on February 25, 2023 Verified purchase

Plug and Play

The Metra 70-1771 was a perfect match for my vehicle. I soldered all the connections which took a little time but it was well worth it. Thanks to Sonic for your support, everything went as good as could be expected.

perfect fit

installed a Pioneer mvh 210ex perfect fit for 2001 Mustang GT made the job so easy with this and the install kit..

Wiring made easy

Perfect way to make a nice clean harness when tying in to factory wiring. Wires are color coded & also labeled to avoid any wrong connections, almost foolproof!

Metra 70-1771

Makes radio installations so much easier. Just prewire the new radio, remove dash trim, remove old radio, plug new radio in and put dash back together.

Good value!

Metra makes good products, would recommend with stereo purchases. Can’t complain it was free on my order. Thanks, Sonic.

By Andrew on June 10, 2020 Verified purchase

Metra 70-1771

Fit perfectly easy installation my stereo works great will buy again

XXXellent foundation for a custom install

After being dissapointed by two different Schoche install kits ( locally ) I ordered the 5804 from Sonic. 3 days delivered by the way. Kudos Sonic, you guys rUUle. I used the kit to mount a Pyle PLD 40MU (which also rocks but it is sold out at Sonic). The Pyle has a Large face on a single din, so a mod to the mounting was required. The Metra 5804 has plenty of extra material to support the dremel excavation. Turned out Fab. Dremel on slow to medium with a cut-off, due to the melt and resolidification. Used a soap stone-bit on medium to clean up, smooth, and blend, etc.

Pros: Purrrfect fit in the 96 Ranger, Extra material molded in for custom hacking, Solid construction and poly material. Super fast service, Sonic rocks.

Cons: I am mechanically inclined, so there is no complaint (maybe when I have to remove for the Video in install, I will whine). 5 minute install, though. My eleven year old daughter could install this kit.

Great product!!!

Worked great!!!!!

Great addition

Ive bought the similar one years ago and I beat it up putting it in a semi but the one in the semi had a disc reader. I got this new unit without the discount reader and I'm loving it 100%. These Alpines never let me down ND has plenty of power plus more if you need it. I love it, you will too.

By Davarius on February 8, 2024 Verified purchase

Alpines last touchscreen-less stereo .

Alpines only/last receiver without touchscreen. It’s ability to process and search through FLAC files is what separates it from not only its competitors but computer based stereos in general. Purchase two on general principle.

By Phillip on February 24, 2026 Verified purchase

Great product easy install .

Love the design of this Alpine unit and the ease of installation. Sleek design good and easy functionality, very quick Bluetooth connection.

By Russell on January 27, 2025 Verified purchase

Works for what I got it for

Got this for my 98 toyota corolla and it was easy enough to install, the longest part of the whole process was connecting the wiring harness to the adapter and actually crimping and getting the cords matched up and straight but even then easy enough.

Got it to listen to music from my phone and works as intended. I love how you can customize and change the display color to match your dash, really neat.

By Anonymous Shopper on April 27, 2026 Verified purchase

Easy to connect.

Aside from a pin being bent a bit upon first inspection, connected just fine for my radio.

By Sontario on February 20, 2026 Verified purchase

Top notch

Excited to get this alpine installed and bumping

By David on January 14, 2026 Verified purchase

Great simple headunit

Just wanting something that works and looks decent.

I put in my 99 Land Cruiser. I was tired of the double din unit I had when I had a drop down DVD player. Now just listen to music on my phone.

This checked all the boxes.

By John on August 15, 2025 Verified purchase

Great head unit for price

I am old school went with alpine single din. Awsome just like back in the days. Great sound , power and versatility. Love the blue style. Plenty of power for my 4 way 6×9 ins. Love it couldn't be more happy. Also bout wiring kit and dash kit to make it look good and hooked up correctly. Thanks

Great harness

This harness was a perfect fit for my kids 03 F150. The plug is well made and the wires are of decent length and quality. It does exactly what it’s supposed to do and is so much easier and faster than chopping off an oem plug to wire a radio in.

By Thomas on February 4, 2025 Verified purchase

Love this Alpine head unit!

Can’t beat the sound quality of this alpine Bluetooth head unit! Easy to install and not complicated unit to use… I love the options of choosing different colors on the display… Three sets of RCA pre-outs will be adding infinity Kappa speakers and a jl audio subwoofer soon
