How to connect?

#include <FastLED.h>
 
#define LED_PIN      1   // which pin your pixels are connected to
#define NUM_LEDS    78   // how many LEDs you have
#define BRIGHTNESS 200   // 0-255, higher number is brighter.
#define COLOR_ORDER GRB  // Try mixing up the letters (RGB, GBR, BRG, etc) for a whole new world of color combinations
 
CRGB leds[NUM_LEDS];

int ledMode = 0;
 

void setup() {
 delay( 2000 ); // power-up safety delay
 FastLED.addLeds<WS2812B, LED_PIN, COLOR_ORDER>(leds, NUM_LEDS).setCorrection(TypicalLEDStrip);
 FastLED.setBrightness(BRIGHTNESS);
}
 
void loop() {
 leds[0] = CRGB::Blue;
 leds[1] = CHSV( HUE_BLUE, 255, 100);
 leds[2] = CRGB( 0, 0, 255);
 leds[3] = CRGB::Red;
 leds[4] = CHSV( HUE_RED, 255, 100);
 leds[5] = CRGB( 255, 0, 0);
 
 FastLED.show();
