Re: O2 Sensor

The 1987 5.7K used a single-wire O2 sensor mounted near the outlet of the left exhaust manifold and connected directly to the ECM through a one-way Weatherpack connector and purple wire.  See the 87 Computer Control Wiring Schematic here.

In other words... if people learn by making mistakes, by now I should know just about everything!!!
