Thanks for the input. Gasoline Fumes: yes, I will be coming CRXFi or not. You might as well bring that harness anyway, but I don't think I'll need it...you never know.
I'm fine with the MAP sensor now - it is indeed part of the engine harness, so its just the resistor box and coil I have to hack up, I think.
I got the oil check valve in - that took a good couple of hours plus the time to get it at the junkyard... all for that little ant sized thing >.<
I decided to bypass the heating coil for now since I don't even have a blower motor... that saves a little time. What I'd really love to know is what the hell this hose is, and especially where it goes.
Edit: so it's a brake booster hose - where does it go?
Thanks for the advice, gents. And thanks for renaming the thread.
