First, take a 7' CAT6 cable. Cut off 6" from one end and strip 1" from both sides. Solder these 6 connections, such that data 2-4 on this CAT6 cable becomes data 1-3 after this connection point. | 6" black ethernet | The other 6.5 feet of black ethernet | |-|-| | Data #2 (blue) | Data #1 (orange) | | Ground #2 (blue stripe) | Ground #1 (orange stripe) | | Data #3 (green) | Data #2 (blue) | | Ground #3 (green stripe) | Ground #2 (blue stripe) | | Data #4 (brown) | Data #3 (green) | | Ground #4 (brown stripe) | Ground #3 (green stripe) | ![[Pasted image 20231024234450.png]] After that, add in two more connections: | 6" white ethernet | The other 6.5 feet of black ethernet | |-|-| | Data #1 (orange) | Data #4 (brown) | | Ground #1 (orange stripe) | Ground #4 (brown stripe) | ![[trunk_additional.png]] --- After that, solder these together: Left: - 6" SAE power - both 6" CAT6 cables Right: - 6.5' SAE power - 8" 18awg power (for LED power injection) - 4-pin JST connector ![[trunk_components.png]] ![[trunk_layout.png]] --- Afterwards it should look like this: ![[Pasted image 20231024234752.png]] ![[trunk_complete_2.png]]
