Was told they were for brake and dome light for truck toppper.
I can't find those two wires, where are they?
I found a single green but it is a ground.
I already know that the pin at the one o'clock position in the big plug provides keyed power but I'd rather leave it alone,

If you have them they should be on the drivers side next to the hood hinge, inside they end right at the fuse block./QUOTE]
Yes, they do....
Best thing to do in cases where you need power from the battery to accessories at the rear or in the bed is to use one of those wires to connect to a switch inside, then out to a relay in the engine compartment that supplies unkeyed power to the back direct from the battery.
You can visit a boat store (boat US, west marine, etc) and get a good power junction box to hook everything up to. Some are sealed, others aren't, get a sealed one.
You can use the box for anything else you want to wire up.
