I installed the GPS and XM antenna cables. Then I began wiring the overhead post lighting. Why relays? Because the only switches I could find were lit when the circuit was on or all the time. I opted for the former but I want the switches lit when the lights are off and vice-versa. So I'm using the relays which have posts to have the circuit be on or off when the activation circuit is hot. Now the switch is wired to the activation circuit and the light is wired to be off when the activation circuit is hot (and the switch is lit). When the switch is turned off, the post light comes on. Since the components are close together and I have service loops for them, it will be impossible to bundle neatly. However, they are not flight-critical circuits and are easily accessible for maintenance through the overhead access plates, so I'm not terribly worried.
