Well. FWIW I haven't run any clutch multifunction switch for around 15 years.
My original separate 1987 type switch broke sometime around 1998 and instead of fixing or replacing it I simply installed the auto trans jumper for it.
I've never felt inclined to do anything about it since...Even when I completely rewired the truck in 2007 when swapping to a 4.0 and adding cruise control.
I regard the clutch safety switch as a solution to a non-existing problem, that actually creates a new problem all it's own... especially as the original switch failing left me stuck until I jumpered the switch.
If I suffer a failure of any kind I tend not to set myself up for sequels of the same failure...
Fool me once shame on you, fool me twice shame on me!
Until you have been stranded 150miles from home by a failure... THIS is why I do not trust automatic transmissions...
Some day I'll tell you about the day in 1982 when a GM Powerglide automatic TRIED to KILL me and nearly did... My Explorer is the very first vehicle with an automatic trans I've owned since owned in the 35years since...
According to my brother who was (until he stopped working for Ford) a Ford Senior Master technician, an expert on automatic transmissions CLAIMS the 4R70W is the best automatic trans ford has ever made, I still trust it about third as far as he'd be willing to shove it up his own ass...
