I am trying to find a trailer wiring T connector to plug into the factory taillight harness on my 2000 S10 Blazer. They seem to make them for every year but the 2000. The only thing I can find requires splicing into the harness, I would much prefer a plug in model. Has anyone found one of these unicorns?

 

Are you able to pull up diagrams for both 1999 and 2001? I'm wondering if there is any difference, could just buy and return if it doesnt work?

 

While I never did find a T-in harness, when I was looking to add trailer wiring to my '98, I did find an pigtail of terminated wires wrapped up at the factory and stuffed behind the bumper. So I was able to solder the wiring connector to those directly to the end of those, for each of the 4 wires needed for my connector. There were actually a couple other wires in the group, that I did not need. Not sure if they are what is needed for a 7-pin or not, though, I never bothered to look beyond the 4 that I was looking to access. Those wires, once I straightened them, were quite long, enough so that I pull the connector end up into the rear cargo area when not in use, to help keep my connector in good shape and out of the elements.

 

Good to hear, thanks for the update.
