Just curious if anyone knows what these wires are for (not apparently used) on my 1990 4x4 Cos. The single blue one with a spade connector on it is in a loom in behind the battery but is not the one for the standard alarm horn (which has the same type of connector). The second 2 pin plug is in the engine loom that is curled up in the slot in front of the scuttle panel. I thought at first it may have been lamda sensor - and one of the wires was the right colour, but believe this is a 3 pin triangle shaped connector. Thanks David

 

Apparently the two pin is for aircon on later models mate , not sure about the single spade one

 

Something removed from the car maybe? Gasoline vapor canister purge perhaps.
I think all A/C connectors by the bulkhead are behind the scuttle panel. If the alarm has been removed, maybe the single wire could be for the hood switch.
