hesco throttle body

Was getting ready to install hesco throttle body on my jeep, and I noticed it has some kind of vacuum port. (pic enclosed) I imagine it is generic for many years of the 4 liter jeeps, and I have a 93 sport 4 liter. I was just going to cap off the vacuum line, I just figured some of the other years might have a vacuum line that go to throttle body, but on my year jeep there is no vacuum lines going to throttle body, so is just capping it off the right thing to do. Figured I'd ask here cause its better to be safe than sorry.

Well I have a 93 and it is a H.O., but the map sensor is on firewall, so should I just cap the nipple off? I can't really move the map sensor unless I got a different mounting bracket and extended wiring harness.
