I thought I'd be able to help, but wrong branch. I worked several of the target designator systems in the Air Force that were externally mounted. On all the aircraft I worked, the external fuel tanks were always mounted to the outboard pylons with the ordinance on the inboard pylons.
As for the position of the FLIR pod. I'd say it's a safe bet that there is only one place to mount it due to having to rewire the aircraft. In other words, that wouldn't be interchangeable like the ordinance. So you might be able to do a google image search of the system and see where it's positioned on the aircraft.
Hope this helps a little.
