mysterious blue and green wires

Can i request a wiring diagram for honda odyssey 2007 ex-l with nav/rear entertainment system/backup camera.I am planning to put DRL and use the high beam spot and also eventually installing fog lights.And also a detailed information on how to do these will be much appreciated.Thank you in advance.And one more thing,while checking drivers fuse/relay bow i noticed two wires one is blue and the other is green both are attached to a connector but not connected to anything,i also found these exact same wires in between the underhood fuse box and the headlights attached to a connector but not connected to anything.Any idea what these wires are for?

Options not on your vehicle.

sorry for my ignorance but can you explain further.

OK as a hypothetical example, pre-wired for a front fog light system. If you don't understand don't proceed by yourself. Have you tried a continuity test on those wires to see if one end is joined to the other?

nope i havent done any test on those wires yet.After reading installation manuals for fog lights from honda, i think i know now what those wires are for.It is prewired from the dealer just incase i wanted to add fog lights, and those 2 wires are for the fog light switch that goes thru the dashboard.

Well score another 10 points for Howard the world's best diagnostic engineer

Joking aside, they would be for fogs and something else, it should only be 1 wire. Here's a simplified circuit.:- A97_fogs.bmp

Howie, It could use both wires...one as control for the relay as you've shown. The other for status of the relay output, as in are the fog lights on, i.e. an indicator on the switch. Mark

Good point especially as you then have the (safer IMO) option of a ground going switch. Although most Japanese stuff is wired as per my diagram plus illumination and grounding feeds at the switch.
