Connecting Vac Line for MSD Opti
The instructions that came with the unit leave a lot to be desired.
The photo they show where the vac line connects is different than my 92 LT1.
On my car, it appears that the vac line I'm supposed to connect to runs to the ASR unit.
For those that have installed their own MSD, where did you connect your vac line? This would be the one that runs off the MSD distributor cap.
I have photo's I can post if it would make it easier to understand my question.
Thanks.

When I put my Dynaspark in I "T"ed off of the vacuum fitting on the intake on the drivers side by the PCV valve for vacuum and drilled a hole in the bellows in front of the TB for feed air.
