Ok, so thanks to Pig75 we've nutted out the idle up.
This is for a Mu - unsure if it looks the same in a bighorn/jackaroo/rodeo engine bay
There are a few solenoids up the back passenger side of the bay.. here you see a blue and white solenoid side by side.
The white one is for the air con idle up
You need a hose coming from the small tube on the back of the alternator/vac pump to the tube closest to the left hand guard and the other tube on the solenoid goes to your idle up actuator on your fuel pump

This is a picture I found in another thread which shows the idle up actuator. It is pointed out in the picture as "Block off?"

I also encountered a problem where my idle up actuator arm was adjusted too far away to strike the idle arm.
Here is how to resolve the problem.

Hope this helps others.
