How 2: Fit JAM FCC To MAP Sensor


Recommended Posts

Many of you connect your JAM FCC onto the ecu, as i have done, but it didn't work as it should, so i connected it to the MAP Sensor.

1st, unplug the Map sensor, theres 3 wires

Cut the middle wire, not too near the plug, as you will need to use most of the wire for connection.

On the JAM FCC there are 4 wires;

ED = 12v live - Conneted to the IGNition behind the key switch.

BLACK = Earth - Connected to the nut holding the MAP sensor.

WHITE - Connect it to the wire coming out from the MAP sensor.

GREEN - Connect it to the other half on the cut wire.

Make sure the White and Green wires are connected to the right place. Or your car will start up funny.
