    MrHorsepowerLSx makes a good suggestion to cut it, out of all the wires on there you will only be integrating a few of them back to work with your factory gauges. Removing it is not that hard. In the center is a tiny 1/4" bolt that holds all the sections together (if yours is like mine, which mine is a 94'). I cut mine about a foot back from where it enters the drivers side firewall for future intergration and left the rest of the harness intact and removed with the engine.

    Here is where the cluster enter the firewall next to the brake booster.



    Here is what the 1/4" bolt looks like that holds it in place. The bolt is recessed into the center of the cluster and can be hard to see. Just put a 1/4" socket into there and back it out.

    Yes it is a torx and the bolt is fairly long.
