!!Filament Runout Sensor Not Working!! (no replies)

I have an ender 5 that I just installed an SKR V1.4 board and TFT35 V3 on. Now I am trying to install a triangle lab run out sensor on my set up. I don't think I have the pin set up right. Sorry, I am new to all this. This is how I have it set up...

// Servos
//
#define SERVO0_PIN P2_00
#define SERVO3_PIN P1_26

//
// TMC StallGuard DIAG pins
//
#define X_DIAG_PIN P1_29 // X-STOP
#define Y_DIAG_PIN P1_28 // Y-STOP
#define Z_DIAG_PIN P1_27 // Z-STOP
#define E0_DIAG_PIN P1_26 // E0DET
#define E1_DIAG_PIN P1_25 // E1DET

Any help would be greatly appreciated!!
