Re: Plug wire length
In general, for those installing pre-cut wires I do the following. I number all the wires as I remove them from the vehicle. Then I hold them all up straight. I pick either the longest or the shortest (depending on my mood and what I have left) and pick the respective longest or shortest of the new wires. I install that new wire in the appropriate position and repeat the process until all the wires are gone or I have two or more left of the same length.
