Does a replacement cap and rotor come with the plug in that the opti harness connects to on the optispark?

 

I'm pretty certain is does not...

 

The harness connector is for the optical cam position sensor, in the back 1/2 of the Opti case. The harness plug is part of the back 1/2, not the cap and rotor.

There used to be an excellent reference by Mike Chaney called "The Optisprk Disection Page". That site seems to be gone, but corvetteactioncenter.com has a copy of it posted:
