General market had an electric fan on the air con condenser. It was to assist the engine fan when idling or in slow city traffic in hot climate. The tube that fits in that gap has a thermo switch in it.
Get a spare T and weld a cap on the small stub.
UK market doesn't need a fan as its never 40°C.
On the up side it is for a CA with oil cooler as JDM didn't have that.
Is the extra hose the carbon can outlet?
