EIS and EFIS data exchange

Hi all,
Trying to get my EIS and Horizon 1 configured to show Manifold pressure on the PFD data box.
Here is my setup:

Dual Horizon 1 with single AHRS and EIS 4000.

GRT manifold pressure sensor attached to Aux 3 input on the EIS
Aux 3 labeled Mprs and AuxSF 200 AuxOff 62 in the EIS setup pages.

PFD set to show data boxes-
Right lower box left top label set to MAP
Right lower box left bottom set to MAP data


The actual data that gets displayed seems to be the same as what is coming in on Aux1 of the EIS. (happens to be the L tank fuel level)


Question:
How do I set the Horizon1 PFD page to display the Aux3 data from the EIS in this PFD box?

Thanks,
Duane

Go to the setup menu (on your PFD), under Engine Information System -- there you can assign what each Aux input's function is..
