Narrative:

Cleared for ILS 36R with the equipment inadvertently set up for 36L causing a possible breach of 36C centerline which was also in use at the time. While opening the approach plate; we received a master caution light for a possible pressurization door open. I placed the approach plate in its holder (which happened to be opened to 36L) to don my oxygen mask while we completed the appropriate items in the flight manual and descended to 10000 ft. We isolated the problem to a switch; bypassed that switch and climbed back to FL240 with just under an hour before descent. ATIS called for 36C and 36R as active. Not noticing the left for 36L was covered up by the approach plate holder; I briefed the approach for 36R using the 36L approach plate. This wasn't picked up on until passing through 36R centerline at which time the PIC began to question his equipment. The final approach controller came on about that time to question if we had the airport in sight. We visually acquired the airport and immediate action was taken to return to 36R to an uneventful landing. We debriefed this event as a crew and the circumstances and human factors that lead up to this event. Things that should have prevented this: better attention to detail by myself and crew while briefing the approach. A great brief is no substitute for briefing the right one to begin with. Better monitoring by the pilot not flying. Go back to basics. When cleared for an ILS and you can see the runway; make sure you are flying to the right one.

Title: C5 First Officer reports briefing and setting up for the ILS 36R using the 36L approach chart. This is not detected by the pilot monitoring and results in overshooting towards 36C approach course before the deviation is detected by ATC and the crew.
