Need help: STECS Space Throttle System–Max

[Sirch]

Hello, I have two questions and would appreciate some help.
1. From the videos, I cannot see how the STECS STEM is connected to the STECS Space SIM when the STEM is mounted on the GNX MFH.
2. Can the STECS STEM be mounted on the bottom of the STECS Space SIM and the STECS ATEM on the GNX MFH? And if so, how is the cable connection between the STECS ATEM and the STECS Space SIM made?

Thank you very much for your help.

Best regards,
Chris

The STEM can be attached to either STECS or MFH, but the ATEM can only get attached to the STECS. Both the 2 modules are connected to the STECS' main body by internal wiring if attached to it.
Please consider that if you get the Mini or Max versions (STECS+ATEM) and wish to replace the ATEM with a STEM you'll also need a new base plate (the STECS Standard base plate).
