use 2 map-sensors??

I swapped my crx-89 a couple of years ago.
I´m using :
B16A2 Block
B16A1 Head
and this year i´ve tuned it up a bit... with:
Cranecams stage3 cams
Integra LMA
Cranecams valvetrain with titanium retainers
Wiseco highcomp.pistons
Golden Eagle rods
Skunk2 Camgears
Supersprint exhaust
No cat
B18C4 exhaust manifold
EFISystems PMS stand alone system
Skunk2 Intake Manifold
and and i wonder if it´s possible of using the MAP-sensor on the B18C4 throttlebody with EFI PMS and the MAP-sensor on the firewall togeather ?
Do they cooperate or must i use the one on the firewall only?

The reason i´m asking this is that I bought the EFIsystem PMS from a friend who bought it from a guy i the US who´d cut the wires to the MAP-sensor.
Usually you just unplug the contact put this middlepart contact and replug the original MAP-sensor cotact.
But since i hav´nt got this middlepart it would be easier for me to take
the original contact from the B18C4 engine-cable-linkage, put it to the EFI-cable linkage
and just plug it in on a B18C4 TB,instead of cutting the original cable and solder the MAP-sensor cables from the original Cable linkage.

Is it possible????
Anyone knows......
