| assuming ur using a mechanical gauge. Run the vac line thru the grommet of hood switch cable on firewall (above clutch pedal) connect (T) to vac line of ur choice, or a vac line where your boost controller reads from ect. run up to pillar or what the hell ever you have gauge in. then connect red to POS 12v source (preferably w/ key on only lighted **test w. test lite.) (I used the IGN fuse and used a special connector to wire it thru the fuse in case it knocked out the circuit, itd be the fuse instead.) Then hook NEG black wire to a chassis ground (I used a screw into the body by TimeControlUnit (d side door under plastic trim) Wabam
