Color of wires to micro switch

[tobluforu]

In an attempt to get the fuel shutoff to work on my 72 mfi, I need to know what the colors of the wires are that connect to the micro switch. The wiring harness that goes to the fuse/relay block located on the drivers side, engine compartment has been taped with three different colors of tape. Black, red and blue and in the process of removing the tape I found two wires taped together which look to be white or maybe gray with a red strip. These two wires are cut and have no connections, but it sure looks like the wires I’m looking for, anyone know if these are the right colors?
Thanks

Mine are grey/red, both wires.

Here you find the diagram:
