03-04 Cobra boost guage

I have a 03-04 cobra guage cluster in my Procharged 02 GT. I'm wondering if I can hook up the boost guage in the cobra cluster. I plan on getting an accurate aftermarket one as well. I'm just curious if i can use the cobra one too. Is the guage mechanical or electrical? Does anyone know where I can get the parts to hook this up?

Thanks, Mark
