As mentioned on the forum, this is my first attempt at Visio. Having said that, I found Visio the easier of the programmes that I haver tried using to make an MGB schematic.

The methods I have used to come to the end result are almost certainly primitive and inefficient, but they work. 

One of the biggest obstacle I came across when starting this project was the ability to create, and easily use, multi coloured wires. Visio allowed this.

There are two additional files (stencils??) in the folder that contain the Symbols used and the Wires used.

If you download all the files to one folder on your computer and then run MGB Wiring.vsdm this should open the visio file plus the Symbols and Wiring files.
