What is connected to the other end of the yellow connector?
It's by the thermostat housing.
Peugeot Dealer kindly left mine loose and dangling down by the gearlinakges...

Engine seems to run fine without it though! Thinking either an oil/water sensor?

Oil level sensor. I guess your oil level gauge doesn't work now...

YES!

When it should be registering at startup it does a few full sweeps, I thought that was because I hadn't reset the service counter for a while and it had gone into panic mode!

Lol, should be fine when you plug it back in, its not connected to the service reset at all.

funny.. i know someone else who leaves these unplugged =D

I didn't did I?  

Lol if I did though.
