2019 Yukon/Trailer 12 volt connection

[Khdllc1]

I have a 2019 Gmc Yukon and need to find out how to get 12 volt power to 7 way plug. Is their a fuse wire I need to install?

Welcome to the forum.

If you are installing an aftermarket 7 way plug, the hopefully quality kit you have should tell you what the kit desires for the source for the 12 volts.

If you have the factory 7-blade, I believe that fuse #67 in the engine compartment fuse block needs to be in place. And I might be FOS:
