TPI MAP, Fans, Questions

[Bob Valentine]

Things are going well with my TPI -> Olds 403 setup.   Ford injectors are
in place, I'm modifying a TPI FP reg. to fit my setup, and have finally
doped out the  harness I have - supposedly 89, but see below for why I
think it's 88.   I've faked out the ECM for emissions solenoids (thanks for
the info guys).  But a few more questions:  

1.  MAP sensor - it looks like the TPI doesn't use a MAP sensor.  Am I
correct?  This is a MAF system (165 / ABYA).   There's no connector on the
harness, and nothing about it on the schematic I have. Am I looking too
hard? ;^>

2.  "EGR Vacuum Sensor Signal".  What is this, can I just leave it
disconnected?

3.  Can I just leave the park/neutral input (B10) open so the ECM thinks
it's permanantly in gear, or does this need to be a real input?

4.  Will the ECM care if the cooling fans are not hooked up?   I'm staying
with the stock clutch fan for now... one less thing to deal with.    Just
dummy up the fan relay with another resistor?

BTW, I was temporarily stumped as to why my harness didn't have a wire on
pin B6 for the VATS input.   A quick search thru the DIY_EFI archives and
the F-body list reminded me that 88 doesn't use VATS.  My cal is 1988 ABYA.
  Of course, this was AFTER I built a VATS eliminator (thanks to Mike R.).
At least now I'll be ready when I want to burn a later prom.....

Interestingly enough, pin B6 (VATS input) does have +5 vdc on it.
