    One less step.
    The wires for the bell already being part of the harness saved a step. I had never done anything like this, but everything connected up and works.

    Reviewed in Canada on September 18, 2021
    Alright so here are my thoughts and comments on the Metra LC-GMRC-01
    I ordered this item to use on an after market stereo in a 2006 Hummer H3.
    So when starting off you look at the piece and you wonder where is going where...
    Yes its as easy as color to color ... with a couple that will make you wonder.
    So
    1. Key lines are only if you have wires to for your streeting wheel controls
    2. Pink goes to your back up cam. Which I don't think they sent on how to red wire on the cam cable.
    3. There was a few wires I didn't have to use so just taped them off
    4. The black chime box works, so there is two connectors the white one for the main wires and the black one with wires. Plug in the black one to the chime box and doesn't hook to anything less but the harness.
    The product came in good shape and is all step up. The only issue I have is that the vidoe plug in doesn't want to click in its spot but not a big deal right now.
    So over all I would recommend this product to anyone who can use it from the list given.
    Wish I took better pictures when it was all wired but in the picture provided shows the stoero is working.
