Metra 70-1858 receiver wiring harness

This vehicle-specific wiring harness makes connections between your new car stereo and your car's electrical system.

First, attach the color-coded wires on your Crutchfield-supplied harness to the wires from your new stereo. If you're not using a soldering iron, we recommend that you purchase some wire connectors to secure the connections. Check out our handy article on three ways to connect the wiring harness here.

Now, once this harness is connected to your new stereo, you'll be able to plug right into your car's factory radio connector. This harness saves installation time since you won't have to cut factory wires individually, and this also enables you to re-install the factory radio if needed. A detailed instruction sheet comes with the harness. Warranty: 60 days.

Please read this important note: This harness may not contain provisions for every wire needed to complete your installation, and it will not accommodate special navigation, video, or factory steering wheel control connections. You will need a special adapter if you want your factory steering wheel audio controls to work with your new stereo.

Connections:

  • 12V constant power
  • 12V switched power
  • chassis ground
  • power antenna turn-on
  • dimmer
  • left front speaker +/-
  • right front speaker +/-
  • left rear speaker +/-
  • right rear speaker +/-

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so, then check here for a list of parts. You can also call an Advisor for more information.

Crutchfield Customer Review (What's this?)

I love having this wiring harness from Crutchfield. With it and the harness that comes with the head unit I am able to sit in my easy chair and connect the two together. Then all I do is take it to the car and plug it in between the head unit and the vehicle's plugs. The process could be easier. The good instructons from Crutchfield help too!

Pros: Convenience, quality, fit, instructions

Cons: None

Written By EJ, Colorado on Monday, May 18, 2015

Crutchfield Customer Review (What's this?)

This Wiring Harness is made to plug directly into the stock (OEM) wiring harness for my GMC 1994 Safari Van & it's pretty slick! No splicing or guessing what wires control what. Just plug this adapter in to the existing wiring harness that plugs into your stock (OEM) stereo system & wire your new stereo as per the instructions that your new stereo comes with. Works excellent!!

Pros: Easy to install Works like it should

Cons: None

Wiring interface

Written By Charlie, Pennsylvania on Sunday, May 17, 2015

Crutchfield Customer Review (What's this?)

Nice wiring interface, good directions, I soldered connections it would be nice if it came with quality connector but a minor detail, directions were excellent, I also had a shop manual for my 98 Camaro so I was able to double check all connections.

Pros: Quality material, easy to install

Cons: Should supply connectors a s part of kit.

Crutchfield Customer Review (What's this?)

I bought a new wire striper and did not need for this it was so simple to use. I wish they told you what wires you did not need for your vehicle. The orange and the 2 blue wires had me scratching my head and I called Crutchfield tech and they helped me through my dilemma.

Pros: very easy to use

Cons: does not tell you what wires are not going to be used.

EASY

Written By R Bertino., Tampa, FL on Wednesday, March 25, 2015

Crutchfield Customer Review (What's this?)

The easiest kit I've ever installed. The wire color matched the factory side so it was just 20 minutes of sodering and heat shrinking the connections. Btw you have to soder to the pioneer because there wires are so small.

Pros: Simple.

Cons: None.

Fits well

Written By MD, Colorado on Wednesday, March 25, 2015

Crutchfield Customer Review (What's this?)

It's about as straight forward as it gets.

Pros: Makes installing a new radio into an old car much easier.

Cons: Should come with the appropriate size and style connectors. Crutchfield offers all of the options that I needed to install the radio except for the electrical connectors to attach this wiring harness to radio harness. Why not throw in a dozen connectors with each harness?

Crutchfield Customer Review (What's this?)

Metra wiring harnesses have been a godsend to the aftermarket stereo market for many years. Gone are the days of hacking the factory harness with trial and error. Basically some crimping, then plug and play.

Pros: Ease of installation. Factory harness in tact.

Cons: Nothing.

EZ!

Written By MikeG, Bakersfield, CA on Thursday, February 12, 2015

Crutchfield Customer Review (What's this?)

Easy to install unless you're color blind. Everything matches up quickly and fits the OEM harness exactly. Everything functions just as the OEM radio did, including the radio continuing to play after turning off the ignition until you open the door.

Pros: Easy to match up after market radio and harness wiring. Fits OEM connector exactly.

Cons: Hooking up wiring from new radio to harness would be difficult for someone who's color blind. I'm not, so it wasn't an issue.
