I have a 52mm electrical prosport boost gauge w/ steering column pod for sale. The gauge has an opening ceremony, and can be set to show either amber or white backlit. Never got around to putting it on so everything is brand new. Will include some assorted wire connectors that I got at radio shack to save you some time. I opened some of it up, but I still have the boxes and will put everything back in place.
Asking: $80

Gauge: http://prosportgauges.com/52mm-boost-gauge.aspx (electrical)

Connecters: http://www.radioshack.com/sm-insulat...i-2103495.html (a couple of packs, bunch of different types)

Keep in mind those prices don't include shipping charges.
