4AGZE mystery pipes and throttle help

[Doylie]

Car - AE86

Motor - 4AGZE (the non-ae101 version)

Problem - I'm doing a 4AGZE conversion into my sprinter, to replace the 4AGE, and I have no idea what certain pipes on the engine are supposed to be connected to. Can you guys please shed some light on what I'm missing? Here are the things I don't know:



What are each of these three pipes/hoses supposed to connect to??

Here is a close up of each of them:



(also, am I missing something where the question mark is? is the TPS supposed to be there or something?)





Also, I have a couple of other issues I don't know how to deal with. This one:



My heater pipes coming through the firewall have been cut, as can be seen here:



So what am I supposed to do with the heater hose that comes out of the back of the block? Do I just re-route it some where? Block it off? I'm stumped..

The last issue is that I have no idea how I'm supposed to hook the throttle cable up to the throttle when it is mounted at the rear of the intake, and facing the opposite way.



Do I need to get a custom cable made up to get some extra length and then run the cable around and back to the throttle? Or is there some other solution that I'm overlooking?

Help on any of these questions would be awesome.

Thanks,
Mark
