The harness coming off of the opti has two slots, and the PCM harness has one slot..

Is the harness from the opti for a different year??

What should i do?

 

If the opti harness fits correctly at the opti end, shave off the tab that is interfering. I think others have had to do this sometimes.

 

Okay, will do.

Thanks
