7 pin Blade connector issues

Having a heck of a time getting the wiring figured out for my trailer. When I bought my truck the 7 pin blade connector was banged up so I bought a new one and wired it up. Only problem is that I;m not getting power to most of the pins. I get running lights and the right turn signal. Thats it. I've even unplugged the factory wiring harness to eliminate that as a problem Any ideas of what else to check to check? Fuses? Relays?

Go to section 18.1 and you can look under "Electrical Diagrams" to see how everything is wired up. Think it also has pin out on trailer plug.

The under hood fuse panel has fuses for the trailer wiring. The right turn and left turn are on seperate fuses. Might not hurt to check them if your original trailer plug was mangled.

Well I checked out the under hood fuse box. I had a blown 10 amp fuse which controlled the left blinker and brake lights I believe, and also had a blown 30 amp max fuse which controlled the rest. Replaced those and everything seems to be working like it should now. Thanks for your help
