Unplug the connector from the TPS. Crimp
the wire tap onto the wire that is grey with a
purple stripe. This wire should be in position
"C" on the connector. Plug the grey wire from
the FI Controller into the wire tap.

Run the wiring harness for the FI Controller
from the engine to the seat. Make sure that it
will not get damaged when you reinstall the
tank. Use one of the wire ties to tie the wires
to the frame, away from the cylinder head.

Place the FI Controller where you plan on
mounting it permanently. In most cases, this
will be under the seat. Connect the ground
lug (black wire) to a grounding point on the
bike. Use the Velcro tape to mount the FI
Controller in position. Use alcohol swab to
clean mounting surface prior to attaching
Velcro.

Reinstall fuel tank and seat.
