Take this with a big grain of salt because I read it from a former pilot in a modeling forum years ago, but none of the fighter-interceptor S's in the ITAF had RWRs. A simple RWR was fitted to some fighter-bomber S's or some G's, and it was an in-helmet tone (maaaybe a single light, I'm not sure), with no directional indication, so something along the lines of the SPO-2 in the Mig-19. The ASA upgrade, that came later in the 80s, added some, in the form of the AN/ALQ-70/72 ECM system and AN/ALE-40 countermeasures dispenser, again only fitted to fighter-bomber squadrons I believe. I don't think the G and S are that far apart in terms of time, both were introduced in the 60s I believe, it would not be a night and day difference besides the Sparrows/gun compromise. The ASA upgrade, with IFF, PD radar, ECM and CM dispenser, monopulse seeker Aspide, and Aim-9Ls would be more 'late model' I guess.
