Default How does LS1edit hook up?

My PCM is hidden behind the center console of my 58 Vette. When I get the engine tuned, does the tuner need access to the PCM to connect the LS1edit cable?

How does it connect?

The tuner only needs access to the diagnostic connector, hopefully whoever wired your car included that in the conversion.

OK great! So they don't need to get to the actual PCM. My wiring harness was made by Howell Engine Developments so I guess they would have included the diagnostic connector. What does it look like?

Click Here to see what the connector should look like, or look under the steering column of a VR+ Commodore.

Some tuners like to access the PCM to reflash it using a bench harness rather than through the diagnostic connector.
