If ya' look in those manuals, the wires are all color coded with code charts. The best things to do,(since your watching kids
), grab some of the colored markers they are writing on the walls with, and color the wires the same color as the chart.
It's a lot easier to comprehend when looking at it and your car at the same time. So far to date, i've taken out my cruise control, AC
w/wire harness, power steering, all AC related items under the hood, put my battery in the trunk, and tucked all other wiring out of site as much as possible!
