Looking at the SCART pinout you either use pin 17&19 for Scart to composite or 18&20 for composite to SCART.
I assume you are using a RCA jack for composite, thus the ring of it would be GND and the tip the signal.
Scart includes connections for composite video.
All you have to do is to wire your composite video signal to pin 20 and the ground of your composite signal to pin 17.
