About the Metra 70-1858 Receiver Wiring Harness

Metra 70-1858 receiver wiring harness

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

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 +/-

Features

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 & sold separately.

I bought it from you guys for couple reasons. Ive ordered from you before and love the support (even late night). I could have gone to auto parts store and bought it there, but they do not have tech support nor do they give you a Master data sheet either. [ Garrett  Dec 13, 2015 ]

Q
My 1993 suburban has 6 speakers. 2 in the dash, 2 in rear doors, and 2 in rear cargo area. This harness looks to be for only 4 speakers. How do I power the two not included in the harness?
[ Larry  Jan 03, 2019 ]

Hi Larry, you will have to splice 4 together. put the dash on the front channel and the back 4 on the other channel. keep the positive and negatives straight.
[ Bernard  Jan 03, 2019 ]
A
Car head units traditionally only have 4 speaker outputs in the wiring harness. Chevy has probably wired the 2 sets of rear speakers in parallel to share the amplifier power from the head unit. You can keep the wiring in that fashion or add an amplifier to provide additional power to the extra set of speakers.
[ Daniel  Jan 03, 2019 ]
A
Rca outputs to an amp powering the largest pair of speakers.....or if your head unit has enough rms, splice into one set of speaker outputs, be it "front" or "rear"

Q
Will it work with the onstar option?

The ability to retain OnStar controls with aftermarket receivers will be determined by the receiver you are using and the vehicle you have. For full information on this type of integration (including the parts you will need) please contact an Advisor by phone or online chat.
