Changing carb engine to FI in 1971 280S

I am helping a friend swap in a Fuel Injected 2.8 engine (was carbureted) into his W108. I have the engine in, but would like some information and photos on the following items:
Coolant hose routing and size (injection pump heater?)
Fuel pump hoses and routing
Where does the temp gauge Sensor go?
Vacuum hose routing
PCV hose routing
How to time the ignition
Where does the remote P S reservoir mount? (Had res on top of the pump of carb engine)
Oil filter housing check valves location
There may be other things, but the above items will help get a lot accomplished.
Thanks, Rich

If you want to come take pics under the hood of my 1971 280SE you are welcome to. I don't know any of the answers. I'm in Altadena.

Starter wiring

When I removed the starter, I seem to remember two small terminals, one on each side of the larger center one. When I installed the starter, I only see one small terminal on the left (outboard) side of the center. I have three small wires, and I doubt all three go on the one terminal. Does anyone know where the three wires go?

Not sure about the starter wiring, but if the rest of the harness is in similar shape I'd keep several good fire extinguishers handy.

No kidding. Fresh terminal nut shows somebody has been in there before.

Obviously no help with the starter wiring, so how about this. I found these parts in a bucket that was eluding me until today. I see how they mostly hook up, but I am not sure where a couple connections go. The unit that is mounted to the engine mount arm looks like a check valve or regulator of some kind. I don't know if the line not hooked to anything goes to one of the hard lines going back to the tank, or not. The outboard side of the fuel filter is not going to anything, and I assume it gets connected to one of the hard lines (pressure from pump?). There is another fitting on top of the pipe connected to the IP, and I don't know what connects to it. I am planning to get the hoses rebuilt. Any help is greatly appreciated. Thanks, Rich
