In the past week I’ve completed a few more wiring diagram pages for my wiring book: the Electroair electronic ignition, the P-MAG ignition and the Engine Info System (GRT EIS4000).  In addition, I took quite a few hours to sit down to figure out what components I needed for my Manifold Pressure & Vacuum system design.  In the pic below I show the 3 newly completed wiring diagrams and my hack PowerPoint diagram that I made to keep track of all the bits n pieces required to build the Manifold Pressure system.

Here is a shot of my Engine Info Management wiring diagram page:

Along with knocking out some wiring diagrams, I also added a couple more diagrams to the list of subsystem diagram pages for the Wiring Book.  I broke out the Starting system to its own page, and to keep track of all the wiring and to have a holistic, systemic, wire-focused (vs component-focused) view of my system, I added a Components Interconnect page.  Below is the updated list that I shared last week (again, green denotes completed or mature, yellow is currently being worked):
