MPFI Conversion/Sensor Q?

[ZC4ME]

Ok, I have most of the stuff to perform the MPFI conversion on my 91 Civic STD. I am concerned about one thing in particular. On the back of my DPFI manifold, there is a sensor which I believe to be the "Tandom Valve Control Solenoid Valve" which is not on my MPFI manifold (which is from an 89 CRX Si), but there is a "Fast Idle Control Solenoid Valve" on the MPFI manifold. Am I suppossed to hook up the wires from the Tandom Valve Control Solenoid to the Fast Idle COntrol Solenoid on the MPFI manifold? This is the only thing that I can figure that I am suppossed to do, which would involve change the actual plastic connector on one or the other.
Also, I have a ZC motor that will be going in eventually, is this the plug that everbody says "has no place to go" when I install the ZC? I know the ZC does not have the Tandom Valve Control Solenoid or the Fast Idle Control Solenoid.
I am not a stranger to this stuff, I have already swapped a B18 into a 2G Rex, but I like to go into things knowing as much as possible. Any help is greatly appreciated. TIA.

peace

P.S. This is my first post here, so hello to everyone and I searched for quite a while before I decided to ask.

Thanks, I have read that and many other write-ups about the DPFI to MPFI conversion and nobody (that I have seen) has mentioned anything about the sensors that I am questioning. I was just hoping to find someone in this forum that has dealt with these.

thanks again

i noticed that as well..I have a plug unplugged and i belive that is what it went to. car has been runing fine for a year or better.

I put that link because it says..."Also when you swap harnesses you will have 1 white plug left over from a sensor that the DX had that MPFI do not, so don't be concerned."

Yup, I understood that, but again my concern is that fact that the (a6) manifold has a sensor on it that the (b1) manifold does not and they really don't look anything alike like the EACV, and TPS and TS do. I have been trying to locate a diagram that shows the ECU pin location for the two different sensors on the two different model designations, but the only ones I have found online were blury or did not contain all the info I was looking for.
