94' FZJ80 -- What is this port and where does it go? (1 Viewer)

[myunrealname]

Hello ih8mud friends, I'm chasing an EGR code 71 on my new to me 94' FZJ80. I noticed a vacuum port looking thing near the location where the EGR modulator vacuum hoses plug in. I'm not sure what this is, and I'm hoping someone here can help me ID this thing. I live in an emissions-free county, and I'd happily delete the PAIR and EGR systems, but first, I'm hoping to figure out what is supposed to plug into this port.
