Bad brake switch?
Switch just behind brake pedal I think is called the brake switch? What ever it is, has it gone bad or what? If you have it plugged in the tail lights stay lit. Also one side is brighter then the other (driver side brighter than passanger) and even with brakes applied in not sure if it lights up as its suppose to when you hit the brakes...???

The brake switch could have shorted internally and keeping the brake lights on. It should have no effect on the tail lights. "One side brighter than the other" I would pull the bulbs and clean the recepticals, make certain the bulbs are installed in the sockets correctly and no crud bridging the contacts. Back the truck up to something so you can get some sort of reflection to see if the brake lights are working. Or, have someone observe when you press the brake.

One suggestion about the light staying on....maybe you need a new one ($8), but I have two vehicles (93 Civic and 75 F250) that need a penny or quarter taped to the tip of the switch to keep it depressed (and thus stay shut off) until the brake is pressed.
On the truck it's an issue of the switch being too short to reach the "stop." Yes, I know the thing is adjustable but it's still just a bit short. In the case of the Honda, the plastic stop broke apart and I just needed a plug to as a stopper.
Low budget but I gotta tell you I spent some time on both before figuring it was not a bad switch, just a bad "stop" for the tip.

Problem fixed. Bad switch, but one light still brighter then other. I took out all the lights and cleaned everything, every single light in truck is brand new no jokes! So what could the problem be?

Could be bad grounds, corroded sockets, or corroded wiring. Is it a huge difference or just a little?

Small difference really. As of you were to put a flashlight up to one side so it's simmer looking and leave the other normal so its bright looking

Righto, there are two different 12V double contact bulbs: Industry #1034 and #1157 / Or #1034NA or #1157NA if amber bulbs.
1034's have less candlepower, Ford only installed 1157's. Remove the bulbs, look at the side of the metal section, the industry number will be stamped on it in black ink.
