Quest for 79SC only owners

[OldTee]

I can use a little help from the 79 crowd. I own both a 78 and 79 SC and the CIS is mostly identical. The key word here is 'mostly'. My question is where does the vacuum line for the distributor go. Does it go behind the CIS, just out of sight, or does it go to the front (in this case the bumper side) of the throttle body? My 78 goes to the back. The 79 was originally hooked to the front. The vacuum diagrams are not much help, at least to me.

I only want to hear from 79SC owners. If you would lift your lid (engine side) and follow the vacuum line hooked to the distributor and let me know I would appreciate it.

To the technicians. There are three ports. The rear two are vacuum wise, the same place according the my vacuum gage. The one on the front displays a different vacuum reading. For example the front one displays some vacuum at idle, the rear ones don't.

Mine was in the front of the throttle body.

Thanks appreciate the look see.

My 79 sc row goes near the back drivers side.
