Installation
1. Check that you have all parts required for installation, and the engine is cool.
2. Disconnect the negative (-) battery cable.
3. Gauge mounts in a 52.4mm hole. Use supplied brackets and nuts to secure gauge to dash.
4. Drill 25.4mm diameter hole where sensor passes through sheet metal (such as firewall) and install rubber grommet provided. (Grommet will require slit.)
5. Securely mount the MAP sensor to the firewall or inner fender with pressure port facing down. (Bracket fabrication may be required.)
6. Install T-Fitting in a manifold vacuum hose. Attach one end of the nylon tubing to the T-Fitting using the compression adapter. Connect the other end of the nylon tubing to the
MAP sensor with the tubing adapter.
7. Connect the white wire to dash lighting or switchable 12V light source.
8. Connect the red power wire to a switched +12 volt source that maintains power during engine cranking. Most vehicles break the electrical connection to accessories while the
engine is being started. If the boost gauge is connected to one of these circuits, the auto zero function will not work properly and inaccurate readings will result. To determine
whether a switched source maintains power during starting, look for electrical accessories in the vehicle that remain on while the engine is being started. Connect the red power
wire to the same circuit that powers one of these accessories. The connection can be tested by turning the key switch from off to on, the needle will move backward to the stop
pin and then move to zero. Once the needle has reached zero, start the engine. If the needle reads vacuum without returning to the stop pin, a suitable connection has been
found. If the needle moves to the stop pin and then reads vacuum, another power circuit must be found.
Power-Up
The needle will move backward to the stop pin and then move to the zero box. This procedure is an auto-calibration function and is performed on every power-up. While this test is
being performed, the gauge may make a clicking sound. This is normal.
Electronic Boost/Vac gauges are equipped with an auto zero function used to compensate for operation at varying altitudes. This function takes a pressure reading during the time that the key
switch "flies through" from the ON position to the START position. The reading represents zero pressure and is used to set the zero point on the gauge each time the engine is started.
