With the Ford starter solenoid and it's exposed terminals, you can bypass it with a pair of jumper cables to get your engine started. No clue on the MBZ one.

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.
