I'm building an S13 for Chumpcar, an 89 5MT chassis with a KA24DE swap. The engine came with vacuum lines, but no AIV (PAIRC) or charcoal canister. My question is what to do with these four vacuum lines that are supposed to run to the AIV and charcoal canister.

Here's a diagram of what I'm talking about:

The four lines that start near the intake manifold is what I'm talking about.

We've got a few issues with the swap and trying to ensure this isn't contributing to anything. Should I just cap off the lines? Should I loop the two for AIV back into each other and do the same for the canister? Should I just leave them unplugged?

I've searched a ton, but haven't really found the information I'm looking for.

Thanks in advance for your help!

cap em, you dont need the pairv or canister. i have neither nor do i have the controller valves, the only two vacuum lines i have are for the fpr and brake booster, all the rest can go away. just make sure you pin open the swirl control valve. and it runs like a champ!!
