Working on the intake refresh of my 89 S4. I ordered the 7-way vacuum splitter since mine is an automatic but found that mine has a 5-way splitter. Just want to make sure this is just one of those odd differences and that I'm not missing any lines somewhere. All 5 of the ports did have a line running to them; I just unhooked the two that are open.
You're fine.
5 way or 7 way with two plugs works. (The plugs are: 900 312 012 02.)
If you order parts from one of the professional 928 suppliers, they should know this stuff inside out and know if they send you a 7 way, you will need 2 of the plugs. Shipping, these days, is expensive!
