Grey wire mod

Is there the need for the grey wire mod on FI models

Can't even find a grey wire!


My understanding is all stateside WRs have the grey wire. There are two connectors under the tank and it is in the middl of one of them, double check. Could be the previous owner already did it?

The "grey wire" on the FI models are the stock ECU; to "cut the grey wire" you replace it with the competition ECU.
