It’s EGT or exhaust gas temperature, some row cars had them iirc Japan, Australia and most Middle East countries. It’s warning that the cat is getting too hot by a sensor next to the O2 sensor. Now you all know why there is what looks like another O2 sensor blank on the downpipe on US models.
Its most likely just a spurious warning if you’re doing spirited driving in hot weather but if it keeps coming on or stays on it could be a blocked cat. If it’s a race car you’ve probably removed the cat anyway so just disconnect the sensor and it should go away.
Not the best of photos, but this is my US '89 S2:
Did a post a few (four!) years back about swapping the bulbs out to LEDs which may be of service, though I'm working with a US model: https://rennlist.com/forums/924-931-...ence-post.html
US 944's and 968's shouldn't have the EX warning light. I have one on my Japanese LHD 968. I haven't heard of Aussie S2's having/needing them, maybe those were Japanese grey imports as they are common in NZ too (in both RHD and LHD). Japanese cars also have a road flare with holder in the drivers footwell and the 968 have clear lens reverse lights.

Kiwi, are you in the NZ transaxle FB group?
My car was ex japan I think like all downunder cars back then. Anyway, yes the EX is for the Catalytic converter system.
Yes mate I am in that group.
But facebook is awful when having a technical discussion and to be quite frank any technical discussion on facebook seems to bring the idiots out of the walls...
