Is this the Correct Forum for my Conversion

I registered and posted a few times here last year but didn't have much to show or related Subaru questions until now. BTW, I noticed I can now add pics so I gave you the quick version. I have 100's of pic's. . Back on track,I dropped a EZ30D w/ a TY75 5 speed into an VW/Porsche 914 which is a mid engined car. I've started the car 10-12 times but never more than a 45 seconds at a time. I haven't made an exhaust system yet so it's loud. I'm at the point where I need the input of some Suby gurus. 1st question; I noticed a 2 pole connector adjacent to the TB which I believe is for the air temp sensor. I did not get the air breather from the donor car, a 2003 LL Bean, so I want to know if I need to connect this to a sensor before the TB or can it be by-passed? 2nd question; I found 3 ground wire from the ECU to control the radiator fans but my set up uses only 2 grounds. A hi and a low. Any thoughts. TIA, Kent
