LT-1 Basic Question

[kenkelly at lucent.com]

Bob,
	I think several of the impala engines used two Knock
sensors. One on each side of the engine. The Camaro &
Corvette only use one knock sensor on the Passenger side. I
believe you must match the knock sensor and the computer,
but you can just replace the knock sensor with one that
matches the PCM. also each year GM added anothe sensor to
the engine, so The harness must match the sensors you use. I
know 94 added the MAF, and 96 added the Crank position
sensor and aftercat O2 sensors.
