Old Ford Solenoid as Glow Plug Relay / Amateur needs help

[Neomagnus2]

I'm trying to wire my glow plugs to a switch in cabin that will enable to turn on and off my glow plugs when I choose to with the flip of a switch.

I got the idea from a youtuber, he did similar work but he still had he original glow plug relay connected for the sensors ( and not to mention his engine is still in the original car)

Anyhow I think I'm close to getting it done but I keep second guessing myself, and the last thing I want to do is burn out the glow plugs or burn out the solenoid.

A - 5 glow plugs wires (running from glow plugs to negative post)

B - brown Wire going to inside of cabin (running from starter post to inside of car)

C - green wire (connected to black thick gauge cable/to starter post on solenoid)

D - black thick gauge wire (to positive post on battery and on positive post solenoid)
