How long does it take to replace engine compartment wire harness

If you know what you're doing about 20 to 25 hours.

About one six pack. Are you changing all wiring in just the engine compartment? If you already have a set made up and your a little experienced at it, between 4 and six hours tops. If your going under the dash, I have seen it take up to six years, but it will take a long weekend and then some.

Before I clicked on the title I was thinking "It depends on how much beer you drink while doing the job." And then I see my buddy above talking about a six pack. LOL If you have never done it before, don't expect it to be a quick job. Get some help. An extra pair of hands will be invaluable.

Then you'll need two six packs.
