After market socket is red, black, black. need assistance to hard wire. brake light acts as parking light and vice versa. switched wire with same results
If you have a test light or voltmeter, turn park lights on and find the one wire on vehicle that is hot-it will almost surely be red or green, as the black is surely the ground wire. Now on the new socket, you need to know this: If those bulbs are two filament bulbs (one filament for park lights, and the other filament for brake or turn or both) the brake light and the turn light will be brighter than the park lights. You can tell the difference in brightness, and the brake lights are always brighter than the tail (or park) lights.
How many bulbs are on this socket? Do you have 2-filamet bulbs or just one filament bulbs? Maybe you can figure it out by looking at the other side, see how or which lights are for tails and which for brakes.
SOURCE: BRAKE AND TAIL LIGHTS DON'T
When the brake lights don't work and the lights are out of the dash it is caused by a shorted light bulb, the brake light and turn signal are on the same bulb. So pull the bulbs out and check to see if they are flat and making contact on the bulb connectors, that's if you have not found the fix for this problem yet.

This sounds a bit crazy, but you do not have a good solid ground to your trailer brake lights. You may have to run a separate ground wire from the trailer to the car. Pull your trailer close to the front of your car, close to the battery. Use some wire to connect your trailer to the battery. Then touch each contact one at the time until you learn which port turns on which light(s). Using the wires, only one in the ground connector and the other in the brake connector. gain access to one or both sides of the trailer lights, use another wire and touch the base of the bulbs to the metal of the trailer if the light gets brighter you need to run another ground wire. Hope this helps FixYa up.
