Move vacuum pump to Z-axis on Genesis v1.2

I’ve 3D printed the vacuum pump mount and housing. But to move the vacuum pump I need a longer power cable. I think I need about 350 cm. Can someone confirm?

The issue I have is that v1.3 also introduced the Farmduino which has different connectors for the vacuum pump cable. As such, I can’t purchase the v1.3 vacuum pump cable from the shop because I need to connect it to the RAMPS board.

Where can I get a longer v1.2-style cable for the vacuum pump?
