Connect a vacuum hose from your intake manifold to the sensor nipple. Secure it with a zip tie.

Make sure to either wrap securely with electrical tape or use shrink wrap to protect all pins upon installation in the engine bay.  Find a secure location to mount the new MAP sensor.

Tips:
It’s not necessary for you to cut off your stock map connector, splice into the wires just before they go into the connector so that you can use it if you ever need to revert back to a stock MAP.
Use a DVOM (Digital Volt & Ohm Meter) to determine which wires of the MAP sensor wiring are 5v, GND and Reference by turning the key in your car to ON (engine not started) and probe with the DVOM.
Refer to the PGMFI forums for further developments for OBD0 and additional MAP sensor BIN files that will work with this sensor.



Typical OBD1 Honda Map sensor wire colors (do not assume this is the same for all vehicles).  Refer to your vehicles wiring diagram for proper wire colors if you don’t have a DVOM.  IF YOU HOOK UP THE WIRING INCORRECTLY YOU WILL DAMAGE THE SENSOR ALMOST INSTANTLY.  There are zero returns or warranties on this product do to its fragile nature.  If you need a warranty, order one of the sensors we stock that does have one, like the Hondata 4 Bar.
