Smile while pressing the brake pedal it wont accelerate

Hello everyone, been looking around and had no luck trying to figure out why my LS3 swapped S10 Blazer won't accelerate when I'm pressing the brake pedal, if I don't press the brake pedal it accelerates. It really sucks because my blazer is 6 speed manual and when I need to take off on a hill its a beach. It'll roll back til the gas pedal activates again after letting go the brake pedal. What can it be? I'm burning the clutch. You know how usually you feather the gas pedal a little while pressing the brake on a hill but I can't do that. If I'm pressing on the brake the gas pedal does not respond. SMH

I'm wondering if it has a wire to the brake switch to cut the pedal, I run a Holley system and it has a safety programed into the DBW to limit throttle position to 10% no matter how far you push the pedal down.
