-connect dead red
-connect live red
-connect live black
-connect dead black to bare metal

It is a circle.

Live car should put some revs on before the dead car tries to start.

In the old days you could get by with one wire (red) so long as the metal bumpers of both the donor and dead car were touching. That was a long time ago though, do not attempt in a Focus.

;)

If you buy booster cables smaller gauge is better and they should be long enough that the cars are parked fore and aft facing the same direction as oppossed to side by side or nose to nose, you can't normally do that on the 401*.

EDIT: if both dead and live cars both have cables then the two sets of cables can be joined together and you could park one behind the other both facing the same direction.
