I have a 95 2500 12v 5 speed and i was wondering about one of the relays. The fuse box inside the cab on the side of the dash has a relay that you cant get out with out unscrewing the fuse box and it looks like it says Time relay. Does anyone know what this controls.

 

The only time relay on our trucks I'm familiar with is a small silver canister, and its purpose is running the halo lamp around the ignition switch.
