Help identify connectors Jap-spec harness

Recommended Posts

On a RHD car they are about 20 inches from the main harness connector just above the ECU. I can't remember where they plug in, but normally the orange ones are for the heater control units. The blue one plugs into the power steering control ECU (very small black box).

 

It just happens I have one of these looms in front of me, here's a pic if it helps others identify what the orange plug goes into. It's not in the same group of connectors that go to the heater control and climate ECU and I think sits somewhere behind the glove boxes or in the ECU area. The orange heater control plugs are about 4 feet further down the loom.

Yep, they're the same ones I posted earlier. The blue one is definetely the PAS ECU, I couldn't find what the orange one connected to. The only plug on the loom diagram which looked the same was the central locking module connector, but I have some doubts...

 

I'll be swapping this loom out at the weekend so if it's not resolved by then will be able to let you know what it is.

There's right load of weighty junk in these cars, isn't there? :) Pretty reliable junk, in fairness, but as cars get more and more complex, electronically, is this REALLY the way forward. New shape Astra, £800 for a headlight unit. That is supposed to be a low end family runabout.... Audi are charging overr £300 quid to renew a gas discharge headlamp bulb on some models. £800 plus for a Ford Focus diesel clutch assembly, parts only???
