Ida from Aerostich has answered many of the questions and promised more answers on Friday.
"The Red Power Lead and the Black Ground Lead are 16". The input and output wires are all 18" long.
The Ground connectors that are provided are 18" long and are 14 AWG. The end which slides into the module has two small tabs on the terminal should be facing down towards the Input/Output wires. The other end of the ground wires is bare. (See picture attached)
All of the wires are bare on the ends allowing for splitting to what ever device that would be desired. Connecting the gray wire (plug position 8) to the battery makes all circuits hot all the time."
