from your link Quote:
On E4MED models, ... The idle speed solenoid, used primarily on air conditioned vehicles, maintains correct curb idle speed whenever the compressor clutch is engaged.


there was recently a topic about adding an idle controller for when the A/C compressor kicks in on here, it was interesting to read some of the suggestions. looks like this carb would do that without any backyard engineering.

the wiring diagram on that page shows an ECU and O2 sensor etc. still nothing concrete as far as exactly which trucks came with this though but there is some codes on the diagram

V8=LS9
K100(06) & LS9 & NB2
K100 (03) (06) & LS9

I know what LS9 is but whish I could figure out what the other codes mean, that seems like it would translate into something I could use to get all the right components.

I am getting the other CCC components I mentioned from that caprice but dont have anything to experiment on with them yet. on the look out for 455s now too and might end up with an engine before a coach. lol I have a lead on an early toranado thats been in a barn for decades. guy says it was wrecked and has some front end damage but not real bad just got to go look at it. its not a for sale deal, but he said he was sure they would sell it.

Edit to add: thats the diagram for the other one, the one that is electronic primary metering, not the one you have and the one Im trying to find.
