verifone said>my 3rd break light, when my lights where on & the emergency break applied, the 3rd light came on, take off the emergency break & it worked like it suppose to. Also when I would apply the breaks the dash light & radio lights got brighter, it happens every time I step on the breaks.
Now the 3rd brake light comes on when I turn on my lights and stays on, when I apply the breaks the 3rd break light gets brighter. All the other break lights are working fine.

The left brake light ground is behind the left tail lamp assembly. The right brake light ground is under the rear package try on the right side. That is above the rear upper of the back seat where your rear speaker's are mounted. If you turn the parking light's on does the third brake light come on?Or do you have to turn the head light's on to get the third brake light to come on?You can check all the ground's to the brake light's if you want but I feel the headlight or parking light ground is the problem. Since when you turn the headlight's on the third brake light come's on. Get a ohm meter put it on low scale ground one side of it. Then touch the other lead of the ohm's meter to the black wire to both left and right brake light's it should read two ohm's or less. Now go to the third brake and ground on lead of the ohm's meter low scale on the meter and touch the other lead to the black wire of the third brake light it should read 2 ohm's or less. Now behind the left head light there is a ground splice pack see if that has 2 ohm's or less to ground from the wire's coming off of that. Also do the same to the right frame rail ground that you found. Check the left front Frame rail ground as well. Also check the black wire to your parking brake switch for a good ground. You said putting the ebrake on turned on the third brake light on so it would make sense that ground was bad. Let me know what you find.
