Can anyone help me figure out what this relay/wiring group is for?
Did the H4 headlight/harness upgrade this morning and in the process, discovered another group of wires/relay already installed. They're not headlight related — I'm thinking perhaps they have something to do with the aftermarket head unit?

There's a relay with a group of wires:
The yellow wire goes from the relay/harness through the firewall.
The green wire is connected to something next to the engine (starter?)
Two wires (orange and blue) look like they used to be spliced and have subsequently been clipped.
The red wire has a connected attached to nothing.
One black wire has a connector attached to nothing.
The other black wire ends in a small antenna(?)

Previous owner hack job. Time for you to trace it out. Make sure none of the bare ends have voltage.
