    Hiding Wires under dash

    What do people do to hide the wires coming up from the transmission tunnel going up to the dash? I am thinking you will be able to see them when you are sitting in the car so I would like to make them a bit cleaner.

    Also what do people do with wires that are not being used but may be used in the future (heater/radio for example)? Do I need to cover the ends or do something else with them for safety purposes?

    At the very top of the tunnel cover I cut a slot for the wires to come up thru. The corrugated covering is black and doesn't show unless you stick your head down low.

    For the unused wires I pulled the ones out I will never use. The others I put a butt splice on and taped them up.

    I'll be building a console what will go up to under the dash and cover that area. That will be where my ac controls will be housed.

    The unused wires, especially ones that could have +12, the ends need to be covered at minimum with electrical tape to prevent accidental grounding. Ideally, there are some crim caps that will give a better covering. Or, can shrink wrap them up. Any way to cover the end to ensure it won't contact ground.

    You can always pull the fuse for an unused circuit too.

    I try to eliminate wires that I don't ever plan to use but there are times when I may want to keep a wire because or a pre-planed enhancement I'm going to install down the road. In those cases I cut the wire clean so no strands are exposed and use heat shrink tubing on the end and ~1/2" past the bitter end. I use a type of heat shrink wire label that works on a Dymo wire label maker. I'll print either where the wire comes from (i.e. Fuse Box 1, Fuse 6) or what the circuit is intended for. The heat shrink insulates the wire and labels it for future reference.

    Another vote for heat shrinking a little past the end of the wire. In addition, use pliers to crimp the over hanging heat shrink while still hot. Seals it up and looks neat.
