Boost guage fix help.....?

[lostsoul]

This is probably a simple fix but I have a digital boost guage and I have it hooked up right except for I think a wire. I have pos and neg connected so the guage is on but its not reading the boost.. my car has been toyed with for so long and I forgot.. is there a boost sensor that needs to be connected and if so where? ahhhhhhhhhhhhhh

umm.. you gotta have a boost sensor tapped somewhere and connected to the gauge to pick up the boost pressure

here's what mine looks like

Didn't you get a sensor with your gage setup? Wthout a sensor you have no way to read the pressure. How about those dreaded DIRECTONS. or at least a wiring diagram.

A brand and model number might help.

that's a Bosch MAP sensor.
lemme look around to see if i can find the PN

EDIT: i'll email Automater and ask if they can provide me with the part number of mine.. although i think it's #12569240

yea.. here is the sensor






and here is the vac connection



+/- wires are connected and the vac hose is going from that bar to the procharger release valve. All that looks normal but I cant figure out whats missing. I have had it working before the great explosion.. hahah.. wtf is michael when I need him
