I recently replaced 1 of the harnesses on my brake lights and I'm at the brake light won't work. I replaced the right rear brake light harness, I don't mean the entire harness I just mean 3 piece connectors that connects to the sockets. after I get that my third brake light stopped working, I used a multimeter and still no power. the socket is good I tried it direct power there's just no power going to it to light up the bulb. should I replace the harness again.

 

Can we start with what year the car is?

Might add the info to your signature so you don't forget this going forward.

 

Its a 93 Accord coupe also known as Cb7's (90-93 Accords) I take pictures of the harness in talking about.

 

the old right harness was bad and I had to wiggle it so I can get the right brake light and the center light to turn on. I replaced it the wires work quite the same but it made the brake light work on the right except for the third brake center light.


RIGHT HARNESS


CENTER HARNESS I REMOVED TO TEST HAVE NOT REPLACED IT YET.

 

Check the GRN/YEL wire coming out of the failure sensor for voltage when the brake pedal is pressed.
