I have my boost gauge (a decent, inexpensive one from JC Whitney) 
stashed in the glove box when not needed. The hose is run to a "T" 
that I inserted a few inches ahead of the ECU hose fitting. This 
arrangement requires perhaps the least length of hose and is probably 
the easiest for plumbing (i.e., access). I didn't like the flimsy 
plastic "T" fittings that seems to be ubiquitous in auto-parts stores 
like Pep Boys. Instead I bought a nice, solid brass T (about 
$2)--made for aquarium pump hoses--and available in many pet shops.

The JC Whitney gauge is lighted, but I've not bothered to hook it up. 
I imagine that it could easily be powered from the glovebox light.
