well, that blue wire near the top is the throttle plunger... it pushes against the throttle to bump up the idle when your AC is on or other conditions that may need a little extra idle...
it looks like it doesn't have any other computer hookups... I will try to search for some info on this carb... never ran across that one before... so before I get us both in trouble, give me some time to check it out... shouldn't take more than a day tops....
