I have a acura 02 and am having a hard time finding the part that goes to the rear brake light itself..It's a small grey box kinda like a relay that four wires lead into..Seems to be a short in there.Fuses were good and the brake switch was also good..Thats what led me to the brake light.So when I ran a light test to it thats where I found the problem.Not sire what it's called but no one seems to know what it is?This seems to be the only # on it PP-T20

 

Try post some pictures of exactly what it is so we can better help you

 

What exactly is your problem? No tail lights?

Are you talking about #14 STOP LAMP FAILURE SENSOR, #37540-S0K-A01
