Where did the 69 RS headlight system get it's vacuum source from? If the L78 had a intake fitting that only accommodated the brake booster, then where did the RS main hose connect to? I currently have a t-fitting in my intake that provides for the booster and my RS system. I know that isn't original, but it works. I'm thinking about putting the correct hard line fitting on my intake for the booster and was wondering where my RS should go? Please look at pictures. 1st picture is my current set up. 2nd is an original L78 fitting with only one port.
