The wired harness built by MidWest Panel builders includes a firewall forward harness for some of the ancillary systems in the engine compartment. There is a firewall mounted fuse panel and wired bundles that connect to the power management relay box provided with the engine. Also included is a pre-wired bank of relays for the accessories that require high-power switching.
Wire harnesses are all routed into the avionics tray
Lower cannon plugs installed from aft part of the wired harness and plugs from the engine side of the firewall connecting to the power management controller for the dual rectifiers.
Midwest Panel Builders supplied a completed bundle for the engine side of the firewall.
This will be terminated on the master solenoid as well as the fuel pressure sensors starter and shunt.
Some connections will also terminate on the fuse block in the picture.
The relay bank is also pre-wired and easily installed on the bottom of the avionics tray.
This wired bundle is secured to the bottom of the avionics tray and a few Adel clamps to keep it out of way of the rudder pedals and my feet.
This bundle is what will eventually be connect to the power management controller on the engine side of the firewall.
These are the wire bundles from the engine harness that will connect the dual ECU also mounted to the bottom of the avionics tray.
There is a small wired bundle for the clock spring on the prop motor that will plug into the back of the prop controller on the instrument panel.
This didn't get routed with the rest of the wires and will be integrate later.
Wired bundles from the engine harness are secured to the back of the avionics panel using some rivnuts and Adel clamps.
There are also a few grounds from the harness that are joined together and grounded to the back of the avionics panel.
