2017 Tacoma taillight wiring harness

Hi, I need help with finding the taillight wiring harness. If anyone can assist me with this is greatly appreciated. Thank you!

 

It is always best to say just what you wish to accomplish when you ask for assistance. Curiosity kills and satisfies the cat sort of stuff. Oh, and always report back on your success.

 

Two position is reverse, red is reverse aka blip.
Triangle is brake. Blue is the brake light (bright) aka stop and green is parking light (dim) aka running light
The flat 3 way is turn, yellow on driver side and light blue on passenger side. That does the flashy. Green is parking light.

white w black stripe is ground, present on all 3 connectors.

 

Thank you Sir, where would I purchase the wiring?

 

Remove the taillight assemblies and there is the harness. Follow it from there.


What are you trying to do?

 

Do you need a brake T for a topper?

 

I have no idea. A dealership said corrosion got inside the wiring so I want to replace it. Forgive my ignorance but I do not know where to buy. Thank you!

 

What were the symptoms of the truck for you to bring it to the dealer?

Upload a pic of the dealer service work order if you will. Hopefully there is a part number and their wording that will help.

 

No taillights. 2nd time it’s happened. trying to attach service order.

 

My bad, first time to upload here.

 

What is the aftermarket harness on your truck?
What aftermarket stuff is on your truck?

 

I don’t know, it was installed before i bought it, frustrating.

 

Find the best local auto electrical shop to repair the situation in your truck. You do not need to buy a new rear frame harness from the dealer.

 

You also may be able to cut the wire back and replace the terminals. Hard to say without seeing it, but if this was caused by someone using a vampire clip to tap the wires back there, hopefully they did it close enough to the taillight that you can salvage it. From the description “due to a wire splice not properly installed” I am guessing that is the case. A new set of terminals would run you $10 tops, and a crimper can be had for another $20. It isn’t hard to do.

This is why I hate vampire clips!

 

Your help is incredibly appreciated and valuable, I’d like to repay you some how??
