Each pair of pads in a front caliper will have a sensor,
so there is a sensor on the left front brake and another
on the right front brake.  The circuit goes to the left
front first, which is why that is the side you want to
short to ground.

If you have a voltmeter, attach the negative lead to
a good ground, then test the holes with the positive
lead.  (Be sure the ignition is on, to provide juice
to the circuit.)  One of the holes should show 12V.
If not, then you may have a break in the wiring
"upstream". As one lister said, look by the firewall.

If you don't have a voltmeter, a test light should
also work. Ground one lead, then insert the other
into each hole. The "live" terminal is the one that
lights the light.

Whichever terminal has 12V, that is the one you want
to connect to ground.
