Starter relay conundrum

Notice when I mentioned 'early" well on passenger cars that year was 69...In 70 they started using a clutch safety switch...
But your truck just by being a truck might have been enough to not get the extra safety but being a 4x4 it definitely doesn't get one, with a 4x4 when your in rough terrain guys will intentionally start the truck in gear with the clutch engaged to help get out of a "sticky" situation...
