Julies, sweet idea on the linear actuator to lift the hood. I have an original style switch on my 50, so I couldn't do that without changing the switch, but it's deffinitely an idea I'll remember.

So far as wiring up the switch, the method I laid out will make the switch hot only when keyed on. My truck is NOT wired up that way, but is hot all the time. This is very handy for timing, compression tests, etc., but there is inherent danger like Julies said. Most Ford starters are strong enough to pull our trucks around AND start them at the same time (I did this once when I lost a clutch rod--it taxes the battery, but does the job) so however you wire your switch, don't underestimate the repercussions of your choice.

Also, depending on the type of wiring in your truck you may or may not need to make connections to various points on the fuse block, starter selenoid, etc. But it sounds like the switch itself is all you're worried about.

Let us know how it turns out.
