1999 Chevy Suburban V8 Four Wheel Drive Automatic 136000 miles
1999 GMC Suburban 4WD 7.5lt
I am wiring a trailer connector. GM has two dead ended wires one dark blue for the trailer brakes and one orange to charge the trailer battery. The GM service manual shows the orange wire connecting to the under hood fuse block stud B. But the stub B is maked "flashers 30A" under the hood and there is currently nothing in it. Do I just need to plug in a 30A fuse in it and the orange wire would be hot? Is Stud B always live? This could drain the Suburban's starting battery if the trailer is connected with the engine off. How do I prevent that? Also I'd like to know how to install a second battery under the hood for trailer? Also how to activate the trailer brakes (the blue wire)? Thanks, Hide
have the same problem?
