As far as mounting the sensor goes, if it's not one of the more expensive
self heating sensors (likely), you'll want it as close to the exhaust
manifold as possible.  An ideal location is from just below the exhaust
flange, down to right past the first bend as the exhaust pipe turns towards
the rear.  The O2 sensor must be kept hot to function properly.  The
farther you mount it from the exhaust manifold, the longer it will take to
start working and the slower it will react once hot enough to function.  If
you simply have no room to install it close to the manifold, you'll need to
purchase the self heating style sensor, which can be mounted anywhere in
the exhaust.

Sorry, but I can't help you with the wiring as I'm not familiar with the
Holley system.
