I forgot to also ask if the wiring harness out of a 95 Z28 the same as the 97 Z28 and if so will it plug into my computer. Thanks Again

 

Are you wanting to use a 1995 engine harness in a 1997 chassis with a 1997 LT1 and PCM?

95 harness will plug into the 97 PCM. TThere will be mismatches with the 1997 body harness connections: Will need to be repinned.

You really need to add a “SIGNATURE”.

There will not be any connections on the 95 harness for the 97’s crankshaft position sensor, after-cat O2 sensors, the EVAP system vacuum detection switch, serial data connection. The 95 ignition coil connector will not match the 97 coil.
