Manual Safety Switch
1979 F350 swapped out C6 and installed 4-speed along with a 460. C6 has neutral safety switch, cannot find any kind of NSS on 4-speed or clutch pedal. How do I bypass the C6 switch so I can start with key, and how can I add something so the clutch has to be in to start ? building truck for 16yr old son and need safety switch !!!

At the top -middle of the firewall there should be a grey connector.
This contains the NSS wiring.
In that you can run a loop wire to by-pass the switch.
Do this only if you feel it is safe enough for the people who drive this truck as this will allow starter crank in gear for a manual trans.

Funny thing you would want a clutch safety switch. My wife got in my 78 F250 and hit the switch without putting in the clutch. -She pushed my daughter's car thru a brick wall...

I would love to hook up the OEM manual safety switch, my doner 79 the 4-spped cme out of did not have one that I can find anywhere, only the wire that hooks to the tranny that I assume is for the reverse light.
