Ethernet cable color pin define for wireless video transmitter and receiver

I need to connect the Ethernet switch to the transmitter using an Ethernet cable. See the picture below. The transmitter only has 4 points for Ethernet: T+ T- R+ R-. But 8 cables in CAT6. Please ask the engineer to tell me which four to use based on color

Please check the below picture.
T+: No. 1 Orange/White
T-: No. 2 Orange

RX-: No. 6 Green
