Fuse box wiring on cab swap

I'm in the middle of a cab swap. Went from extended cab short bed 6.0, to a crew cab gas cab. So far has been a relatively painless process, and I have gotten pretty far. One thing i am hung up on is the back of the fuse box. I pulled the entire harness from the diesel cab, other then the harness behind the sheet metal in the door posts. I had thought that the cab itself would be the same between the two. However, hooking everything back up, two plugs seem to be missing, the two that plug into the pink slots on the back. Looking at my old diesel cab, the two plugs are in the cab harness, but I don't see them in the gas cab. Does anyone know what these would control? The only real difference in the cabs electrically is the factory brake controller in the diesel one. Or maybe someone with a gas truck knows if there is anything plugged into the two pink slots? Thanks for any help, just trying to not overlook something that could be important.

Cant help specifically with what might plug into those, but I do know that fuse boxes differ between trim levels. For instance, if there's no power windows, mirrors, locks, etc. such as in an XL trim truck, there won't be anything run into the doors. Also, the fuses and traces for those sockets would be missing from the fuse box for those functions, so you can't expect it to be plug and play. The instrument panels are also different between gas and diesel.

Good luck with your swap. I think your only hope is to get hold of a set of wiring diagrams for both trucks, or swap EVERYTHING electrical between the cabs.
