Hi Everyone

I have just replaced my Delta 6 faucet with the Shurflo unit and have a ques=
tion about wiring.

I believe the switch on the old unit was bad so the previous owner installed=
 a manual switch underneath the sink so I'm not sure as to the original wiri=
ng.

From the back of the drivers seat are three wires - one red and two white. P=
.O. spliced into the red and one of the white to install the switch and  dis=
connected the original in-line water pump (yellow/black) wires.

I am now reconnecting the original black/yellow wires and have removed the p=
revious owners switch but there is an extra white wire from under the driver=
s seat that I'm not sure what it is for?

Sorry for the newbie question - I don't have a volt meter and the Bentley di=
agram is confusing me further.

Thanks - John.
