I have a '76 Mav that I yanked the old leaking C4 out of and put in a really strong C4S auto out of a '73 donor. My question is...

Where do the vacuum lines to the tranny solenoid go? I should have taken pictures but I seem to recall that BOTH of the lines from the C4S went into the "4-male" vacuum splitter on the firewall.

Of course this would make no sense as both lines would draw off of the same vacuum source!

Any help here would be greatly appreciated as I have absolutely no downshift unless I use the shifter. Would be nice to put it into drive and have it working normally!
