Default I need help wiring a sensor to hydra 2.7

AEM 0-100psi pressure sensor. It has 3 pins:
1) 5v power supply--- supplied from ecu 5v power supply pin
2) input signal---- goes to aux input 1 ecu pin
3) signal ground----?

pretty simple.
Except the signal ground pin on my ecu (GB11) already has 2 wires on it. Stock narrowband sensor and flex fuel sensor. Im worried that adding this 3rd sensor to it might overload it. thoughts?

Open your hydra software and look up "Request type for aux port 1"

Talks about how to setup the hydra to create the appropriate sensor values. BB03 is that available open request on all 99+ miatas.

enjoy

I would probably hook the signal ground to GB11 and not worry about it. It is a ground, it will not be overloaded.

Thanks. So once I get it wired in and have the Input request type for aux port 1 set up, can I just go into sensor calibration and fill out the voltage/psi table?
