Schematic

I've managed for the past 45 years to get by with the manual-sized schematic when the need required.  My current (no pun intended) project required an extensive and in-depth dissection of a wiring harness inclusive of all new connections from one end to the other and the manual size drawing wasn't  working for me.
Kawboy has, in the past, advocated the advantages of having an enlarged wiring schematic and his advice has never been more true.  Without these enlargements my brain and likely the harness, would have gone up in smoke. 
16X24 and 24X36
The ease in tracing continuity can not be over stated !
Now.....thinking out loud.....what a great companion to this........to have some laminated Blue Prints of the Mikuni Carburetors.  Well....at least the scans..........Just saying !
     

There's something psychological about the larger drawing making the electrical tracing less intimidating. I was reluctant to blow the drawing up to 24 x 36 for fear of losing definition of colors. Now me thinks I'll have to have one printed up that size and see how it looks. Laminating them after printing is the "cream cheese iciing on the cake"
