Location for a cutoff switch and starter draw

The 23 coupe I recently acquired had a cut off switch under the driver's seat that had failed from a load when the plastic base melted, it is also going to be a pain having to lift the seat or reach into the trunk to get to it to operate it .
I have a good quality switch to replace it but was thinking about putting it behind the left splash apron on a bracket attached to the frame. I may have to get on a knee to reach under to get to it, but it would be high enough to be in a fairly dry area.
Any comments appreciated.
I am also putting a 6 volt starter solenoid on it using the foot switch to trip it. Reworking some battery cables as the starter does not turn the engine over very fast. I put a woven strap from the frame to the hogshead and no change.
One question I have on cables and draw. The cable from the battery to the solenoid appears to be a 1-0 size. The cable from the switch to the starter is just over 2 feet long and smaller than 1-0 in size.. could my starter problem be located there. The ground cables are 1-0 in size.

The original 6v Ford starting system works great when everything is in specs. My advice is to yank out all that new stuff and return to original...no cut off switch, no solenoid, no local auto parts battery cables. If your 100 year old starter still turns slow like a tractor with a dead battery your starter needs a rebuild, if your starter has never been rebuilt it needs a rebuild, if your starter was repaired by a previous owner it needs a rebuild, and by rebuild I mean buy one from a reputable model T starter/generator rebuilder.
