GPS Module Connections

The GPS module should be connected first. Slide the GPS cable through the Hubble connector until
enough wires are exposed to make the proper connections to the screw terminals. Tighten the
Hubble connector hand tight to make a secure seal around the cable. Connect the other wires as
listed in table # 1. Notice that some of the wires have been cut off and are not used. Make sure there
are no bare wires touching the PC board or any components on it.
