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!

Good

I purchased this radio back in May for my 1994 Ford ranger. It fit perfectly and was easy to install. It worked perfectly. I am very happy with my purchase and I recommend this radio and the company to all my family and friends. The staff is great and when you call customer service you are treated like family. Keep up the good work.

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

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

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.

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 Unit

The radio is insane, the features are pretty impressive especially for the price point. I do however wish the radio was a little easier to navigate deep into some of the menus. Having the app is an extremely nice feature for setup and audio options, i do wish you could bluetooth to the unit without having the app.

By Brandon on June 18, 2024 Verified purchase

Fit like a glove. Was very happy with the way it went in.

Sounds great. Good features. The only con is the instructions that they sent with it do not explain enough about all the features had to look online for some and the others I just sat there pushing buttons and figured it out. Not done yet but I do like the unit.

By William on July 4, 2024 Verified purchase

Easy to connect.

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

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.
