If you do not have the towing package then no there is not and the BLUE wire for the breaks stops at the safety wall.
If you have the towing package the you will have the small relay box beside the big fuse relay box and wires plugged into the two plugs (C149 & C105) on the drivers inter fender.
Wiring with and without the tow package.

If if I just clip the blue wire at the cab side of the fire wall and run blue wire to the back will I be able to run my controller off the factory plug under the dash?

I don't have the factory tow package on my '97, but I plugged my brake controller into the plug under the dash and it does work without any additional wiring. You might check it with an ohm meter before you start splicing wires.
