July 15, 2020 – Work continues on the panel and avionics.
I started the connection for power to the VPX. This wire will run from the ANL fuse to the power lug on the VPX.
I located and installed the EMS module for engine management. I decided to drill a hole in the sub-panel for a length of conduit so all the EMS wiring can run straight from the firewall back and come in right next to the EMS module.
Here’s the wires coming through the firewall.
I decided to label all the wires in this bundle, so I can just grab the wires I need for a particular component and finish the wiring. I found the pinout and wire list for the engine sensor connector and rang out each wire. This confirms that the pinout is correct, and leaves out the guesswork.
I relocated the manifold pressure sensor from inside the cockpit to the outside, so I don’t have air hoses running through the firewall, only wiring. Then I found the appropriate wires for the sensor, and terminated and installed them.
