I spent all day on the project today starting with producing & installing the main grounding wire for the engine then the coolant sensor wiring for the 1/3 side. I decided to reposition the MAP sender as I think it may have become contaminated with fuel. I'm covering all the wiring with braided nylon sleeve and terminating the ends with glue lined heatshrink. So far I have the coolant, oil pressure, oil temperature, fuel pressure & airbox temperature wires routed to the firewall connectors with the fuel flow & manifold pressure (MAP) to go.
