5. Opening the Harness

We will be removing all of the outer covering of the MCM/BCM harness.

This is where you will start to feel worried about how you will ever put this back together so it looks normal, but it is actually not so difficult to do. Everything in the harness we will be taking apart back here is just taped together, with some plastic tubes in some places. The key to making it look stock when it is back together is to look carefully at how the tape has been applied now before you remove it. Look how the inspection label is held on with tape, how the connector end was taped, and where the tape stopped.

5. Opening the Harness

Don't go too far
Wire ties Can be saved if you know the trick
Remove the tape
Find the end of the tape and remove all of it. If you need to use scissors, do it with utmost care, as you do not want to cut or bare any of the wires in this harness. Gentle and careful go a long way here.
