where goes those 2 connectors

[QuebecmkIII]

After having change my injectors to 550cc my supra run like a crap...
But does these connectors is the possible cause?
where they goes?

the first one looks like one of the VSV plugs (it sits under the inlet manifold,) one does fuel pressure other does egr I think(not sure As mine has been binned).

Not sure on the second one.

first one looks like a vsv or injector connector.

1st pic: route it down thru the lower manifold and it plugs into a plug that is connected to a hard vac line that runs under the manifold. The colors match so it is easy to find.

2nd pic: This plug connects right up against the firewall into a black plug. It is litterally sitting against the firewall

I know where the plugs go but I dont have names for them or what they are for.

If the red one go to the vsv, I don't have it...
I buy the car with no vsv and before I change my stuff he run fine...
