Adding a diagnostic port.....
 

Has anyone added a diagnostic port (OBD) to a conversion?

I have a 91 3.6 in my SC and I have nothing else to do but waste time and source used parts. :rolleyes:

So no one has done this?

It will not require much effort other than getting the 964 round connector
and connecting it to the DME ECM. All that's needed is to connector four
wires, i.e. ground, +12, and K & L lines, since communication with just
the ECM is needed. Most of the Porsche junk yards should have the connector
for a low price as there isn't much of a demand. One could also hookup
the CEL too which would be nice to have.

OK, what would involve adding a check engine light besides having an extra idiot light in the dash?:rolleyes:
