I have a 2019 Tahoe LT 2wd that did not come with fog lights. I purchased the required OEM parts online and started the install. The brackets and for light assembly was fairly easy, the new OEM dash switch was also fairly easy, however the new wiring harness is another story. Does anyone know were the harness is located and how to access it? Any help would be appreciated.

 

post a link to the kit you bought

 

Wasn't a kit, OEM factory parts.

most models 2007 and newer...don't have wiring to options the vehicle isn't build with. Sometimes there are Factory options kits...ie dealer install kits....heated seats, 2 way remote start etc...that can be added...you buy the kit and it comes with everything that's needed. What you bought is replacement parts for a truck built with that option. todays vehicles are computer networks; so adding options could require module programming if you want to integrate it to work like a factory build.

the factory fog lamp wiring harness is probably part of a complete bundle. Ask the dealer parts department if you can get the harness. if its part of a complete front end harness it will be $$ and your best bet is to wire it in as a stand alone light switch.

 

Thanks, the switch is prewired to the fuse box. Just need to run power to the lights.

 

Were you able to get this working with the parts you listed in this thread?
