OBD1 into 80 Monza

[Fastmax32168]

I am in the process of sorting out a 92 Z24 harness to use in my 3500/Monza swap.
I need to know if I need to hook up either of the following in order for the ECM to function properly. Can I just pull the pins or do I need to ground them?
PIN D13 Idle speed power steering pressure switch
PIN F7 Evap emissions purge selenoid
Also what do I have to do about the EGR pins E9, F4, and F5 so as not to throw a code?
Thanks

I wish I had something useful to add other than "please post pics".
A 3500 in a Monza is definitely worth seeing.

if you account for them not being there in the tune, you can do whatever you want with those circuits. ideally, i would hook up the power steering switch since it's used to raise the idle speed when the power steering pressure jumps high, but i imagine your steering rack doesn't have the provisions necessary, so not a big deal.

You'll have to tune it anyways like Robert said, when you get to that point just turn off the EGR and the CCP.

In for pics

There are no pics of the motor in the car just yet, but here are a few of the car.
I sort of did this car backwards from most of my projects. Doing the motor last.
So the purpose of the power steering wire is to raise the idle when it is grounded?
If so that could be applied for multiple uses.

Hell yeah!
I wholeheartedly support this build

correct, when grounded that circuit either adds IAC counts as a precaution to keep idle speed stabile, or it actually raises the desired idle speed in the ECM and adds IAC counts anyway.
