HELP intake coolant line

[Dishtowel]

Hey guys, WHERE does this bloody line go??? I dont know where the red line goes to, , the green one was obvious. I'm buttoning up the cooling system and this is my last hickup.

If you have a EFI please let me know where to run this line to!

that looks like the vaccum line to the brake booster if you ask me. I haven't been under the hood of a EFI 302 in a little while but that is definitely a vaccum connection.

Thanks for having a look, but I am 99.99% sure it is coolant. When I blow compressed air into the green tube it comes out the red one. The other end of the green hose is connected to the intake water jacket.
The brake booster line comes from underneath.

It's coolant. It's helps cool the EGR gasses before it gets into the engine. Without it you might have part throttle detonation or backfiring. If you removed EGR, then it's not needed. Some sites suggest using a tee reducer on the coolant lines to the heater core. My '87 Marquis had this setup, but I can't remember how it was routed..
