Soon, I will be replacing my rear bumper. I am going to replace all the taillight/backup light lenses, bulbs and gaskets while I'm in there. I was wondering if I should replace the harness for good measure or just inspect the original one thoroughly and repair it if needs be. Everything works back there it's just old.

Any suggestions?

 

I would do an inspection. Are the wires brittle and cracking? If not then its a personal choice.

 

X2. If still in good shape, just reuse it.

 

Thanks!
