S&S Cycle T124V Engine VFI for 1995 1/2-1998 Chassis - Manual (Page 3)

RELOCATION OF ThE BAROMETRIC PRESSURE SENSOR (1999-'01) - Procedure based on instruction 51-1145 Section F
Parts Needed:
• S&S® 55-1037 Baro/MAP Sensor Kit
• S&S 55-1599 Baro Sensor Relocation Harness Kit
IMPORTANT: Recent calibrations for 1999-’01 models require relocation of the Barometric Pressure Sensor. Be sure the calibration you are using is
configured to use a MAP (Manifold Absolute Pressure) Sensor before performing the procedure below.
1. S&S manifolds are equipped with a rear manifold hose fitting. If you are using a stock or aftermarket manifold not equipped with a hose fitting,
one must be added downstream of the throttle plate.
a. For independent runner systems, use the supplied #13 drill bit to drill a hole in the top of the rear manifold. Press the supplied hose fitting
into the rear manifold.
b. For common runner systems, a similar procedure can be used. The MAP fitting must be located at the top of the manifold. We recommend
finding a central location where the manifold is relatively thick and the MAP sensor will not interfere with other components. Some
manifolds may already be equipped with a MAP sensor mounting boss or hose fitting. If not use the supplied #13 drill bit to drill a hole in
the top of the manifold. Press the supplied hose fitting into the manifold.
2. Remove the orange OEM rubber sealing grommet from Baro/MAP sensor (if applicable).
3. Cut the supplied hose about 2” long and mount the Baro/MAP sensor on the rear manifold. Attach a zip tie to each end of the Baro/MAP hose
and tighten.

Note: The Baro/MAP sensor must be installed on the rear manifold hose fitting for independent runner systems for proper engine operation.
Installation on the front manifold will result in an incorrect signal to the VFI module.
4. Attach the connector to the Baro/MAP sensor.
5. Run the harness along the backbone of the motorcycle to the stock location of the baro sensor. Make sure the harness does not touch any hot
components of the engine.
6. Remove existing stock barometric pressure sensor and connector; the connector will need to be cut off.
7. Match the wire colors of the relocation harness to the wires of the stock harness. Use the supplied hardware to butt splice the wires together
and insulate the connections with heat shrink.
