You could use a vacuum solenoid (as I did initially on my swap) but you'd need to put a pinhole in the line to bleed off vacuum when power is off (so you can start the engine). I'm currently using a Mazda EGR purge valve for mine. If you source it at the junk yard, grab the electrical pigtail for ease of installation.

You can modify your glow relay to use the 80amp fuse and the glow harness if you want to work well with the Ford solenoid. (Details here - http://www.peachparts.com/shopforum/2985078-post8.html) Some people have had problems with the solenoids, but I've had mine (pulled at the junk yard) in for 108k miles without a hiccup.

What's the black box by the throttle linkages?

Could i just use all the stuff to start/stop the engine that is in the car? That'd be cheaper

Edit: I also used a toggle switch for GPs instead of a push button like everyone else. In the summer it's 5 seconds glow time. In the winter it can be 45 seconds + and I wanted my hands free while that was happening. I like being able to flip on the switch, put on my seatbelt, check mirror adjustment, sip my coffee, or whatever before starting the truck. I have a bright red indicator light and as everyone predicted, I still left them on a couple times. Added a very loud annoying buzzer, and it's been good since. I ran my indicator light from the same relay-power-out that runs to the glow plugs, which is a much better indication that my GPs are actually getting power than just off the switch that kicks the relay.

I used an emissions solenoid from the original Toyota gas setup for a shut down.

You don't need the in-tank pump, but you'll definitely want to remove it. If you look through my build thread you'll see where I extended my fuel pickup with a piece of hose.

Ask away. I spent over two years researching my swap and still annoyed the snot out of these guys with questions. Hopefully I can give something back to the forum for all the help.

So I need two starter solenoids, one for the starter and one for the glow plugs. For the glow plugs can i just hook them to a starter solenoid, switch, fuse and battery or do I need more stuff?

My thread and Yoda's and others have a treasure trove of info and are really worth the read if somewhat snooze-inducing. Pretty much all the "usual" issues have been solved in a number of different ways in our builds and annoyingly shared in stupid detail on our threads

You didn't, your post was very helpful.

That looks identical to the one I picked at the junk yard...should work fine.

What black box? Pictures?

You could, but the integration would be far more complex. For example the stock shutdown is a mechanical valve on the back of the ignition switch. You'd have to find a way to remove the ignition module from the steering column and install it in the target vehicle....not something I'd attempt. One way or another you need a vacuum valve to accomplish the shutdown.....OK, I lied - you can just run a length of vacuum hose into the cabin and when you want to shutdown the engine just suck on the hose! (I know it works because my original vacuum solenoid failed when I was 2500 miles from home on one of my cross country road trips and a temporary length of hose got me home)

Or you could just "T" a vacuum source to the shutoff and run a hose into the cabin. When you want to shut down the engine, just cover the end of the hose with your finger.......Rich

While that would work, vacuum leaks are difficult enough to find and fix without making one intentionally.

....nevermind - I forgot he's going manual, so that would just take the place of the VCV's intentional vacuum leak.

Here's an interesting potential solution I just found - dirt cheap and simple.

Could even be an anti-theft device! What thief in their right mind would push/reset a big red switch that was unlabeled.
