IAT2/boost sensor specifications?

[FinnCobra]

I have swapped Terminator engine in my 1994 Cobra, project is nearly finished. I have 2003 original repair manual and Alldata access but I can't find where Boost sensor wires are connected, or what kind of signal they are giving. I have Mach1 ecm, and I'm using IAT2 instead of IAT in maf sensor, so I can adjust spark according to that. I can connect boost signal to dpfe signal for logging, if it has analog curve. Apparently ECM won't even use boost signal, I searched Terminator calibration in Binary Editor and there is no transfer curve, is it only used foor boost gauge in cluster?
Does anyone have more information?
I found connector picture and iat swap help, but not boost signal specs

The MAP sensor is part of the IAT2 sensor in the 03/04 Cobras. As the Mach doesn't have a MAP sensor there won't be a direct connection. And if you're making more than 14psi it's not useful anyway. At least I think it's 14psi.

The boost gauge in the dash is analog. There's a hose that runs from the a connection behind the blower through the firewall to the gauge.

Does Terminator ECM use boost signal for something, because there are no hints in software? Mach ecm has inputs I can use for logging. Ecm can't do anything with that data, but it makes analyzing easier.
I think I have to check values by handpump to calculate voltage/boost ratio because there is no information.

It might have something to do with figuring out load and spark. But I never actually logged boost to see how/if it affected anything. I set up my spark table the same way I did on my 01 cobra. I never tried to set up any kind of MAP sensor for my 01. I ran it up to 19psi with no issues.
