So did you already tap into a vac source, or did you just connect all power and color wires and not know where to go to find the source?

If you already t-tapped into a vac line, make sure you check all the connections for a leak to the sensor which you should or should have mounted somewhere in the engine bay. Then check all the wire connections to the sender unit. The prosport gauges are very touchy from my experience atleast. Make sure everything is plugged in fully to the back of the gauge ect.

Well the plug with 4 wires is just for power and lighting. Red connect to a 12v constant which you said you did, and black to a good grounding spot. You'll need to connect your other two wires on that harness. If i remember right they were white and orange on mine, and determined the color night and day depending on how you connect them to the lights and acc.

The plug with 3 wires is for your boost/vac source. Run that bundle through the firewall and connect it to wherever you mounted or will mount your sending unit with the same color wires coming off of it. Connect the supplied hose to the bottom nipple of the sensor, then put the air filter somewhere along that line in a logical spot. Then (im not sure of your setup) but you'll want to t off a vac line on or around the intake manifold. There are lines on the left and right side.
