I have a brand new 60psi gauge from isspro. This is an electronic gauge, not mechanical. I ended up using a 40 psi gauge so I do no need this one. The gauge is brand new in bubble wrap. I do not have the plastic connector that plugs into the back of the gauge from the harness side. Isspro would probably send you one for free as in is just a cheap plastic plug that clips on to the wire harness. PM me if interested.
