wiring schematic program ?

I went to a local Office Depot and had them pull up 73 Duster wiring diagram and picked out the one that I wanted. They made me a black and white copy for like $0.79 and I had them blow up a big color copy for like under $3...


I appreciate the advice, but long story short, what I am doing is taking a stock 87 dakota, using a newer vehicle fuse-relay box and adding circuits.. 2 fans, 2 headlights, fuel pump, etc. I am wanting to draw the relay panel, wire colors and where they go etc. I am planning to put a 5.9 magnum in the truck... Just want to keep everything as neat as possible and in order.
Thanks again
