Tail light ground

^^As above^^ Get your correct bulbs back in, the brake pedal properly back together and see where you are at.

Good places to check "stuff" is the left kick panel connector which is where the rear harness separates from the dash harness, at the TS switch connector coming out of the column, and the brake light switch and the fuse panel.

You can download wiring and factory service manuals, free, over at MyMopar. Some of those came from the guys here at FABO

What year is your vehicle?

A good way to check for a battery drain, if there's nothing obvious, such as lamps, is to remove the battery ground and put a 12V test lamp in series with the battery ground. Try to look at the bulb in subdued lighting. Any glow means you have a drain.

If the bulb is dark or only barely glowing CAREFULLY!!! set up your multimeter for the high current (amps) scale and see if there is any reading. Hook one probe to the disconnected battery NEG post and the other to ground such as the cable ground clamp.

Remember!!! Ammeters, current measuring, goes in SERIES.
