My newest 300D, a (non California) 1984, has a bunch of disconnected vacuum hoses. I tried copying off my 1983 and 1985 to no avail. It seems no two are alike!

Wondering if anywhere there is a photo or diagram of the vacuum hose connections for a 1984. It is February date of mfg., if that matters.

Thanks!

Dont use 1985, the tranny stuff is different. Stick with the 83 diagram, it should be closer to your car. If someone doesn't post a closer diagram, ill find something later tonight.

no sticker under the hood?

Could not find a sticker about vacuum connections under the hood. Unless it is hidden somewhere, it isn't there. If it was on the hood insulation, that is gone.

The '83 also looks different from the '84.

Vacuum schematic sticker is usually on the radiator support.

See post 3. Note that item 63 is a short plastic tube with a specifically sized orifice.
