I am now going to solder the Garmin 18x GPS to the DB15 connector for the RTCM.
I am a little confused by the labels so is this pinout correct?
RTCM — GPS
GRX ----- TXD
GPPS ----
GND ------ GND
+5V ----- Input Voltage
GTX ----- RCV
RST -----
Is this correct? There is also a “measurement Pulse Output” wire, but I don’t know what to do with that.

Nevermind, I found this on the archives, I am going to use this
RTCM GPS 18x LVC 6 GRX <-- Rx Data 6 Green 7 GPPS <-- Pulse
Output 1 Yellow 8 GND Ground 3 Black 8 GND Ground 5 Black 13 +5V -->
Vin 2 Red 14 GTX --> TX Data 4 White

Thanks, Do you think I am right on the everything else, the GRX and the GTX ( does rx connect to tx or does rx connect to rx)

The GPPS is likely designed to connect to a GPS Pulse Per Second - which is likely the measured pulse thing…
Caveat - I know nothing about the RTCM, but I do know some about interfacing GPS modules for other purposes.

That is the most important wire. It is the GPPS wire, which provides the precise pulse-per-second needed to get timing.
The rest looks right.
