Fordzilla

My center console project has progressed (if progress is the right word) to the point where I need to tie in to various circuits...For a lot of it (radio, chargers, inverter) I'm just running new wiring for power and grounds, but in adding a number of lights, I'd like to use existing circuits to power my new relays...Specifically, does anyone have the wire colors for parking, low beam, high beam and turn signal lights and a convenient place to access them for my limited vision and arthritic hands?...The truck in my sigline is a generic SLT with no fog lights, just plain piperacks, as a discount clothier once described his store...

I'm sure the suggestion will be made to obtain a factory manual, which I need to anyway...Anticipating that, what good sources are recommended for a poor but honest retiree?...Thanks for looking......Ben
