greddy electronic boost gauge!

[mattspyder]

im confused on how the hell to hook this up or even if i can hook this up. ALL i have is the gauge and the wires that come out from the back of it, thats it, i dont know if im missing some other parts or not. anyone have any ideas on where i hook this up? i also have the greddy egt gauge but with no wires, can the wires that i have for the greddy gauge go with that gauge maybe??

Well you should have an air line that goes from your intake mani to the gauge and then some wires for the power and ground right?

my apexi boost just had : power/ground wires and a nipple for vac source

my apexi egt gauge had 5 diff wires and the harness for the probe. only used 3 [ red/black/yellow ] the yellow was for the idle power [ not on position ].
