Anyone know how to make the cargo lamp next to the 3rd brake light stay on while the vehicle is moving. Factory sets it so it turns off at certain speed.

 

I believe it's like that because it's illegal to have a rear facing white light shining.

I'd say go to the forscan stcky thread and ask this question. If it can be done that's how you're going to do it. (FORScan)

 

Rewire it, Forscan will not help

 

Find the feed wire and tap a direct feed from the battery with a radioshack (well, their replacement whoever you get your stuff from) switch to toggle it on and off somewhere in the cab. Otherwise, no.

 

That's on purpose, so you don't blind people behind you with a white light on at night.

 

Probably that's the intention for those who drive behind you with a high beam.
