It's only an A/C. Drop the whole system out. Call it weight reduction 😉. That's what the removable T-tops are for. When hot, remove. 😂😂

Oh yeah my bad I see it now, not sure what it is. But looks like Reddtarga has shed light on it.

My motor has a plug in exactly the same place to but not plugged into anything, and I have also seen other ADM Gen 2 NA models exactly the same,
Probably because the same loom is used on various other Toyota models and that plug is not used on the SW20 ADM NA

No Sprigs , im referering to the other cable with the white tape on the end next to the main plug, the both come out of the same loom ....

Someone has cut this & taped it up

Well in the first picture you posted that connector was already plugged into the A/C idle vavle. I'm guessing you unplugged it to get the hoses connected and forgot to plug it back in?

If the A/C is switched off the idle up valve should be closed if it is working properly. (which you could check)

My Gen 2 NA normally runs and idles fine, but if I disconnect the hose going to the intake manifold (post throttle) the motor will race, because it is the same as opening the throttle.
The other hose is pre throttle so it probably won't affect much if it is disconnected except let unfiltered air into the intake hose and ISC.

You have not indicated how well (or otherwise) the motor was running with the hoses disconnected.

The a/c idle up valve raises your idle rpm when A/C is turned on, but if its faulty it could explain why the hoses were blocked off.

Idles lumpy now with hoses connected .
So the sensors stuffed?

That's right it's the A/C idle up control.
One hose goes to a 'T' connection that goes to the the intake hose, and the other goes to the top of the
intake manifold (the one closest to the bulkhead).
Looks like you have the hoses sitting there anyway. Are they just not connected?

I think it's the valve which raises the idle speed when the air conditioner is on.

I got this little clean up toy .
Lots done , lots more to do as I learn more ...
But ..
Whats this ? And why isnt anything connected to it ...?

Look at the part with the electrical plug on it & two hose ports going out the bottom of it .
