Terminated the Grnd wire for the Engine Monitor. It also has 3 other Ground wires coming out ot the harness which is to be used for things like the Fuel Flow Sensor which doesn't get grounded by the body of the unit. Things that have ground wires from the device can use these grounds so that they are grounded at the Engine Monitor rather than the frame of the plane. I also ran all the Radio stack power wires (RED) back through the sub panel and into the Fuse Panel compartment.

Ground block continued. I will need to clean up all the harness loops for future removal.
