I have a 96 ka-t. I am almost done the swap. I have a this vacuum line to contend with.. Used to go to the intake, where can I put it now?

Also, what should I do with this connector that used to be on the airbox?

I am using a s13 enthalpy tuned ecu with s14 jumper harness. Here is a pic of the motor for reference

For the first hose, I know you can block it off.

The connector... I cant remember the exact name for it but I do not know about if you need it or not with a turbo setup. Not 100% sure so someone else will have to answer for that.

The connector you're referring to isn't needed, its a non metered air temp sensor (wont throw code either). the vacuum line you're referring to passes through the throttle body and can be eliminated on the back of the head where you will find a three way zinc plated splitter that needs the port plugged and you can braze it with a torch and solder or you can screw a bolt into the vac line or circumvent the spliter with a plastic vacuum t from the parts store. there's many options but it sounds like you haven't done the emissions removal processes like egr and pcv. I personally took my intake manifold to a welder to have the ports tigged up for 20$. I've also used ebay squid style block off plates. there's a million ways to skin your cat.

I removed the EGR setup and used a block off plate. There was a solenoid that the bpv valve was connected to I removed that as well. I will braze or plug it shut thanks.

As for PCV I have the pcv removed and in place a straight fitting with a hose coming off for now, will probably hook to a catch can. The PCV distribution branch is plugged.
