The S1 and early S2 had 1 coolant temp sensor underneath the inlet manifold in the centre and had a yellow plug on it. This is for the fueling system
The brown one is a thermo time switch and is only to control the cold start valve.
The later S2 88 and 90 spec had an additional sensor on a T peice at the back of the inlet manifold near the runners for cylinders 1 and 2. This is for the ignition system.
