Worst case scenario: P/N 56018807 WIRING, Taillamp Socket lists at $11. 66 each at your nearest Mopar parts counter. I replaced one on my model year 2000 Ram about a year ago.
The part number & description are from the model year 2000 parts book. The price is from my receipt. The description on my receipt is "WIRING-LIS". The socket from the factory had basically liquified and become gummy for some reason???
