AP1 swap into BMW 2002.
New to the forum. Recently purchased a 1974 BMW 2002 and also a F20C1 for the power plant. I'm learning as I go and this is my first real in depth build so any help is appreciated.
So far I got it on a test stand and just started reading about the wiring and examining diagrams. My goal is to remove all the unnecessary items and get the engine to turn over on the stand.
Removed the AC compressor and got a shorter belt.
1.) First questions is the bypass hose is just needed for smog correct? This has no effect on cooling circulation in the block right? I want to remove it if its not hindering anything. Also from the diagrams I have looked at the other tube coming out of the thermostat (not radiator hose the one without a hose) is the heater hose. I'm not going to be running AC or heater so I can plug that up?
2.) On the back I have three hoses in question. First is the one on the rear of the intake, which would be the vacuum for the brake booster so I can plug that for the time being. Below that I'm not sure what significance that hose has can it be plugged? the bottom one is another heater hose so I can plug that sucker too?
now for some wiring fun. This is what I was able to snag with the engine. Its the ECM with 2 out of the 3 connectors. My question is whats the third? Also the blue one... no clue what thats for yet. I'm still trying to find good wiring schematics, however I just started my search so if anyone can send me some good information regarding the ECM and what I need to get this started that be great.
Thanks for any help and I will be posting quite frequently as my progress continues.

I may be wrong, BUT, I think that the blue connector goes into the underdash harness, and that harness talks to the gauge cluster and such and then goes back into the ecu.
BTW, love this build already.
