What are these wires for?

[compint]

Hello,

We have a 2006 FR Georgetown 340TS. I am probably getting too old for this but In poking around behind the dash, I noticed 2 wire leads for options that did not come with out model. I believe one wire harness is for fog lights and the other possibly overhead defrost fans. I purchased a factory replacement fog light kit and I am in the process of trying to install fog lights and wanted to see if anyone knew what these other wires in the same area behind the dash would be for? On is a blue wire that has a specific connector on the end. The other pairs are a red and white and an orange and white. I wondered if these should be connected or if they are for something else other than the fog lights?

Thank you in advance!!
