I want to unplug harness at juice box ontop of fuse box and see if m y truck still runs so i can use the attitude for gauges and stuff. Can I do this or do i need to completely remove everything and get sep[erate gauges. Im also doing this because truck is going into stealership in near future.

 

I don't know if thats a good idea, you'd be better off with this: http://www.edgeproducts.com/product.php?pk=81&pvk=247

 

no you cant. the only monitor that can do that right now is the quad commander
