12v at trailer connector
I am installing an auxillary back-up light system on my 99 Silverado. I have the factory 7 pin wiring harness but it does not have a 12v source. My instructions say to refer to the owners manual for missing fuse or relay but there is no refernce in my manual. Can any one help? Bob
