Mark,

Q1. Updated my system drawing. It is attached. If the drawing is correct, my only concern is the wiring between the ST60+, RS125GPS and the D244. (the SeaTalk 1 network)
A1. Your drawing appears to be correct.

Q2. The GPS's other 3 wires will not be connected? (will be insulated)
A2. Negative. The RS125's red and green leads will be spliced to the red lead of a SeaTalk Cable which will in turn be connected to the D244 SeaTalk Junction Block. RS125's brown and black/shield leads will be spliced to the shield lead of the aforementioned SeaTalk Cable. Finally, the RS125's yellow leads will be spliced to the yellow lead of the aforementioned SeaTalk Cable.

Q3. The ST60+ and the GPS will get power AND data from the yellow and shield connection?
A3. Not quite. See the response to Q2.
